areas of page_sidebar() and page_navbar() (with a sidebar) were made to be a fillable containers even when fillable = FALSE. (#1188) - Fixed some typos in the documentation. - When bs_theme(brand = FALSE) we now correctly do not apply brand theming when a _brand.yml file is present in the project. (#1196) - Sidebars from page_sidebar() and layout_sidebar() are now resizable on desktop-sized screen widths, allowing users to resize the sidebar width as desired. (#1217) - sidebar() gains a fillable argument to support vertical fill behavior in sidebars. (#1226) - sidebar_toggle() is now officially deprecated in favor of toggle_sidebar(). (#1235) - Fixed an issue where nav_panel_hidden() could create navs that were still keyboard-discoverable. (#1264) Changes in version 0.9.0 (2025-01-30) Breaking changes - The navbar-related style options of page_navbar() and navset_bar() have been consolidated into a single navbar_options argument that pairs with a new navbar_options() helper. Using the direct position, bg, inverse, collapsible, and underline arguments will continue to work with a deprecation message. (#1141) Related to the above change, navset_bar() now defaults to using underline = TRUE so that both page_navbar() and navset_bar() use the same set of default navbar_options(). In navbar_options(), inverse is replaced by theme, which takes values "light" (dark text on a light background), "dark" (light text on a dark background), or "auto" (follow page settings, the default). This change affects that default navbar foreground and background colors for Bootswatch preset themes with Bootstrap 5. Detailed instructions for customizing the navbar appearance, especially for Bootswatch themes, can be found in ?navbar_options. (#1146) New features - bslib now supports unified theming with brand.yml. brand.yml lets you theme your Shiny apps, Quarto documents and more with a single, portable YAML file. Learn more in the new Unified theming with brand.yml article. (#1148) Improvements and bug fixes - navset_card_pills(), navset_card_underline(), navset_card_tabs() fixed to now respect header/footer arguments (@tanho63, #1024) - Fixed a bug in bs_themer() (and bs_theme_preview()) that caused it to stop applying changes if a Sass variable was NULL. (@meztez, #1112) - Optimized for better performance the internal functions that compile Sass to call the color-contrast() algorithm. (#1140) - input_switch() and input_dark_mode() can be included in Shiny's bookmarking feature. (#1166) - Fixed an issue with the Shiny preset (bs_theme(5, "shiny")) that caused a floating underling to appear when a nav_panel_hidden() was used and active. (#1170) - bslib now uses navbar markup with Bootstrap 5 that's closer to the expected markup for Bootstrap. We still include the navbar-default or navbar-inverse classes on the

element, for backwards compatibility, but in apps that use Bootstrap 5 these classes have no styles. (#1146) - The following functions are no longer marked "experimental": accordion(), breakpoints(), card(), input_dark_mode(), input_switch(), layout_columns(), layout_column_wrap(), page_fillable(), page_sidebar(), layout_sidebar(), sidebar(), popover(), tooltip() and value_box(). Changes in version 0.8.0 (2024-07-29) Breaking changes - To help reduce the potential for squashed content, the main content area of page_sidebar() and page_navbar() with a sidebar now have a (customizable) minimum height and width on a "medium-sized" window. To revert to previous behavior, set theme = bs_theme("bslib-page-main-min-height" = "unset", "bslib-page-main-min-width" = "unset"). (#1057, #1059, #1084) - card_image() had a couple breaking changes (#1076): - fill now defaults to FALSE to avoid stretching/shrinking the image vertically (and thus, changing it's aspect ratio). To restore the previous behavior, set fill = TRUE. - container now defaults to NULL instead of card_body. As a result, card_image() no longer has padding around it, making it easier to create "full-bleed" card images (for example). To restore the previous behavior, wrap card_image() in a card_body(). New features - card_image() gains several new features (#1076): - alt is now a formal argument and is set to "" by default. This default value marks images as decorative; please describe the image in the alt attribute if it is not decorative. - border_radius now defaults to "auto" by default, in which case the image's position in the card will automatically determine whether it should receive the .card-img-top (first child), .card-img-bottom (last child) or .card-img (only child). - file is designed to accept a path to a local (server-side) file, but now recognizes remote files that start with a protocol prefix, e.g. https://, or two slashes, e.g. //. Local files are base64-encoded and embedded in the HTML output, while remote files are linked directly. To use a relative path for a file that will be served by the Shiny app, use src instead of file, e.g. card_image(src = "cat.jpg") where cat.jpg is stored in www/. - The open argument of sidebar() now includes the option to place a sidebar that's always open on mobile screens above the main content with open = list(mobile = "always-above"). (#1088) Improvements - Adjusted the border color of checkbox and radio buttons to match the border color of the input group in bs_theme(preset="shiny"). (#1038) - On mobile, the main and sidebar content areas of a layout_sidebar() no longer overlap with the sidebar toggle button. (#1084) - bslib now re-exports htmltools::css() to make it easier to specify style declarations. (#1086) - Example apps provided with bslib have now moved from examples to examples-shiny to take advantage of the new package argument in shiny::runExample() with shiny >= 1.8.1. For example, try shiny::runExample("build-a-box", package = "bslib"). (#1049) Bug fixes - toggle_sidebar() once again correctly closes a sidebar. (@fredericva, #1043) - bslib now avoids re-defining its components when used in a context where they are already available, e.g. in a Quarto dashboard. (#1045) - Improved the appearance of cards with sidebars and headers in the Shiny preset, especially when custom card color themes are used, e.g. with text-bg-primary or other Bootstrap utility classes. (#1056) - When card_body(fillable = FALSE), bslib now preserves flow-layout margin bottom settings. (#1073) - Fixed a bug in layout_sidebar() that caused a spurious and confusing error message. (#1081) Changes in version 0.7.0 (2024-03-29) This large release includes many improvements and bug fixes for newer UI components like layout_columns(), card(), and sidebar(). In addition, the new input_task_button() offers a drop-in replacement for shiny::actionButton() (to prevent multiple submissions of the same operation) as well as pairing nicely with the new shiny::ExtendedTask for implementing truly non-blocking operations in Shiny. New features - Added input_task_button(), a replacement for shiny::actionButton() that automatically prevents an operation from being submitted multiple times. It does this by, upon click, immediately transitioning to a "Processing..." visual state that does not let the button be clicked again. The button resets to its clickable state automatically after the reactive flush it causes is complete; or, for advanced scenarios, update_task_button() can be used to manually control when the button resets. - Both card() and value_box() now take an id argument that, when provided, is used to report the full screen state of the card or value box to the server. For example, when using card(id = "my_card", full_screen = TRUE) you can determine if the card is currently in full screen mode by reading the boolean value of input$my_card_full_screen. (#1006, #1032) Changes & improvements - For sidebar(): - The page-level sidebar for page_sidebar()/page_navbar() is now always open (and not collapsible) by default on mobile screens. To revert to the old behavior, set open = "desktop" in the sidebar. (#943) - open now accepts a list with mobile and desktop values to control the sidebar's initial state on each screen size, choosing from "open", "closed", or "always" (for an always-open sidebar that cannot be collapsed). (#943) - The collapse toggle now has a high z-index value to ensure it always appears above elements in the main content area. The sidebar overlay also now receives the same high z-index on mobile layouts. (#958) - Improved card(full_screen = TRUE, ...) accessibility: - Full-screen cards are now supported on mobile devices: the Expand card button is revealed when a user taps on the card (thanks @Damonsoul, #961). - The Expand card button is now accessible via keyboard navigation and appropriate ARIA attributes connect the card with the expand and close buttons. - For JavaScript-oriented users, the expansion/collapse is now accompanied by a custom bslib.card event with the full screen state reported in the event.detail.fullScreen property. (#959) - Improvements to the default theme (i.e., Shiny preset): - In the default theme, cards now use a slightly smaller shadow and the same shadow style is also now used by popovers. (#998) - Increased spacing between elements. This change is most noticeable in the layout_columns() or layout_column_wrap() component. In these and other components, you can use gap and padding arguments to choose your own values, or you can set the $bslib-spacer (Sass) or --bslib-spacer (CSS) variable. (#998) - For layout_columns(): - col_widths now sets the sm breakpoint by default, rather than the md breakpoint. For example, col_widths = c(12, 6, 6) is now equivalent to breakpoints(sm = c(12, 6, 6)) rather than breakpoints(md = c(12, 6, 6)). (#1014) - When col_widths has a breakpoints() at lg or wider, it now uses a better default column width for the smaller breakpoints not listed in the col_widths value. That said, you can always include sm or md in your breakpoints() definition to have complete control over column widths at those sizes. (#931) - When row_heights is a non-breakpoints() object, that value is used for the row heights at all breakpoints. Previously, it was used for the row heights from "sm" up. (#931) - When an integer value for any breakpoint is provided to col_widths, a 12-unit grid is always used. For example, breakpoints(md = 3, lg = NA) will pick a best-fitting layout for large screen sizes using the 12-column grid. Previously, the best fit algorithm might adjust the number of columns as a shortcut to an easy solution. That shortcut is only taken when an auto-fit layout is requested for every breakpoint, e.g. col_widths = breakpoints(md = NA, lg = NA) or col_widths = NA. (#928) - Underlying logic moved from R to Typescript to improve the portability of the component. (#931) - value_box(), layout_columns() and layout_column_wrap() now all have min_height and max_height arguments. These are useful in filling layouts, like page_fillable(), page_sidebar(fillable = TRUE) or page_navbar(fillable = TRUE). For example, you can use layout_columns(min_height = 300, max_height = 500) to ensure that a set of items (likely arranged in a row of columns) are always between 300 and 500 pixels tall. (#1016) - page_sidebar() now places the title element in a .navbar container that matches the structure of page_navbar(). This ensures that the title elements of page_sidebar() and page_navbar() have consistent appearance. (#998) - as_fillable_container(), as_fill_item() and as_fill_carrier() now always include the htmltools fill CSS dependency. This means that they are no longer usable with the $addAttr() htmltools::tagQuery method; authors should instead pass elements to the as_fillable_container() and as_fill_*() functions and use the css_selector argument to apply fill options to specific elements. (#946) Bug fixes - Fixed an issue where the page might be given a window title of NA if the primary title argument of a page function, such as page_sidebar(), is NULL or a suitable window title could not be inferred. (#933) - card()s (and value_box()s) now correctly exit full screen mode when they are removed from the UI. If you want to update a card without potentially exiting the full-screen mode, update specific parts of the card using uiOutput() or textOutput(). (#1005) - Fixed a handful of update_popover() bugs. (#747, #1017) - tooltip() and popover() now work as expected when inserted into a navbar/navset via nav_insert(). (#1020) - uiOutput() and conditionalPanel() no longer result in unwanted double padding when their parent container uses gap for spacing multiple elements (e.g., layout_columns(), page_fillable(), etc). (#992, #1031) - page_navbar() and navset_bar() now validate and transform padding and gap arguments into appropriate CSS values. (#991) - Fixed an issue where the xs breakpoint in a breakpoints() object used for row_heights in layout_columns() would override all other breakpoints. (#1014) Changes in version 0.6.2 (2024-03-22) Increased the version requirement on the {sass} package to 0.4.9. As a result, font_google(local=TRUE) should no longer fail to download font files. Changes in version 0.6.1 (2023-11-28) Bug fixes - Fixed the CSS for the bslib-page-dashboard class in the Shiny preset to correctly support page_sidebar(class = "bslib-page-dashboard") and page_navbar(nav_panel(class = "bslib-page-dashboard")). (#917) - Fixed a minor bug to allow the themer demo to be run directly, outside of bs_theme_preview(). (#918) Changes in version 0.6.0 (2023-11-21) Breaking changes - bs_theme() now defaults to preset="shiny". This provides an additional set of theming defaults and rules that make it easier to create Shiny apps (in particular, dashboards) that look good out of the box. To revert to the previous behavior, set bs_theme(preset="bootstrap"). (#711) - value_box() no longer defaults to theme_color = "primary". To restore the previous behavior, please use theme = "primary". In addition to the default style change, the theme_color is now deprecated in favor of theme. (#758) - page_navbar() now defaults to underline = TRUE, meaning that navigation links in the navbar now have underline styling by default (set underline = FALSE to revert to previous behavior). (#784) - page() now returns a tag instead of tagList(). This change allows page() to treat named arguments as HTML attributes for the tag, making it possible to add page-level classes or other attributes. (#809) - The JS/CSS assets behind {bslib} components (e.g., card(), value_box(), etc) are all now bundled into one htmlDependency() and included with the return value of bs_theme_dependencies() (previously they were attached at the component-level). (#810) - layout_column_wrap() no longer requires width and width is no longer the first argument, meaning that width must be named if used. The new default is width = "200px", which combines with fixed_width = FALSE to produce a responsive layout where each column is at least 200px wide. This means that, in most cases, layout_column_wrap() can automatically layout an unknown number of items without you having to set width. (#853) New features - The default version of Bootstrap is now v5.3.1, upgraded from v5.2.2. The most notable thing that comes with the update is the ability to toggle between light/dark color modes purely client-side (i.e., no calls to Sass required). (#749, #764) - Added input_dark_mode(), a new input control that provides a toggle button that can be used to switch between the dark and light modes when using Bootstrap 5.3. By default, dark mode is applied automatically if the user's operating system is also in dark mode. App authors can toggle dark mode programmatically from the server using toggle_dark_mode(), and if you provide input_dark_mode() with an id, you can read the current color mode via the corresponding input value. (#787) - Shiny's Bootstrap theme preset is now used by default in bs_theme() and all related page_*() functions in bslib. This theme brings a fresh new design to all Shiny apps and dashboards created with bslib. This dashboard design anticipates heavy use of cards for organizing content, and works best with a gray background for contrast with minimalistic white cards. This treatment can be enabled in page_sidebar(), page_fillable() and other page_*() functions by adding the bslib-page-dashboard class to the page container or body tag. The preset can also be customized using the $bslib-dashboard-design and $bslib-enable-shadows Sass variables. Set these to false to disable the dashboard treatment and card shadows, respectively. These variables can be set via bs_theme(), e.g. bs_theme("bslib-dashboard-design" = "false"). (#897, #906) - value_box() has been updated with a number of new features and improvements: - value_box() now supports many new themes and styles, or fully customizable themes using the new value_box_theme() function. To reflect the new capabilities, we've replaced theme_color with a new theme argument. The previous argument will continue work as expected, but with a deprecation warning. (#758) In addition to the Bootstrap theme names (primary ,secondary, etc.), you can now use the main Boostrap colors (purple, blue, red, etc.). You can also choose to apply the color to the background or foreground by prepending a bg- or text- prefix to the theme or color name. Finally, we've also added new gradient themes allowing you to pair any two color names as bg-gradient-{from}-{to} (e.g., bg-gradient-purple-blue). These named color themes aren't limited to value boxes: because they're powered by small utility classes, you can use them anywhere within your bslib-powered UI. - Added showcase_bottom(), a new value_box() layout that places the showcase below the value box title and value, perfect for a full-bleed plot. (#758) - showcase_left_center() and showcase_top_right() no longer take two values for the width argument. Instead, they now take a single value (e.g., width = "30%") representing the width of the showcase are in the value box. Furthermore, they've both gained width_full_screen arguments that determine the width of the showcase area when the value box is expanded to fill the screen. (#758) - The showcase_layout argument of value_box() now accepts one of three character values: "left center", "top right", "bottom". (#758) - A new Build a Box app is now available online or via bslib. See ?value_box() for details. The app helps preview a set of value boxes while you configure and customize their appearance and provides you with code to copy and paste into your app. (#790) - Added new navset_underline() & navset_card_underline() functions as well as a underline argument to page_navbar() to leverage the new nav-underline styling on navigation links. (#784) Improvements - The bs_themer() app now supports previewing the dark mode variant of Bootstrap 5 themes. (#767) - Improved the style and appearance of the button to enter full screen in card()s and value_box()es to better adapt to Bootstrap's dark mode. (#780) - htmltools::save_html() now works as expected when applied directly to components (e.g., card(), etc) and pages with a non-default theme. (#823, #815) - layout_sidebar() received a new design. The button to collapse and expand the sidebar now appears at the top (instead of the bottom) of the sidebar. On mobile devices, the sidebar now fills the layout_sidebar() area as an overlay, rather than expanding from above the main content area. Note the max_mobile_height argument of sidebar() determines the maximum height of the sidebar area on mobile, but it now only applies when open = "always". (#798) - layout_sidebar() now uses an

element for the sidebar's container and a

element for the sidebar title. The classes of each element remain the same, but the semantic meaning of the elements is now better reflected in the HTML markup. (#580) - In layout_column_wrap(), when width is a CSS unit -- e.g. width = "400px" or width = "25%" -- and fixed_width = FALSE, layout_column_wrap() will ensure that the columns are at least width wide, unless the parent container is narrower than width. (#851) - bs_global_theme() gains a preset argument to match the function signature of bs_theme(). (#896) Bug fixes - toggle_switch() now works correctly when called from within a Shiny module. update_switch() worked as expected, but toggle_switch() didn't apply the module's namespace to the id of the switch to be updated. (#769) - Filter controls in the popovers of DT::datatable() tables now better match the current Bootstrap theme and are responsive to the dark mode setting in Bootstrap 5.3. (#267, #775). - A double border no longer appears when an accordion is used inside a sidebar(open="always") context. (#795) - layout_sidebar() no longer gives the sidebar main content area the role="main" attribute. (#580) Changes in version 0.5.1 (2023-08-11) New features - Added tooltip(), update_tooltip(), and toggle_tooltip() for easy creation (and server-side updating) of Bootstrap tooltips (a way to display additional information when focusing (or hovering over) a UI element). (#662) - Added popover(), update_popover(), and toggle_popover() for easy creation (and server-side updating) of Bootstrap popovers. Popovers are similar to tooltips, but are more persistent, and should primarily be used with button-like UI elements (e.g., actionButton(), bsicons::bs_icon(), etc). (#702) - Added input_switch() and update_switch() for easy creation (and server-side updating) of a Bootstrap's switch input (an on-off toggle for binary input values). (#483) - Added two new toggle functions: toggle_switch() for toggling the state of an input_switch() element and toggle_sidebar() for toggling the state of a sidebar() element (sidebar_toggle() remains as an alias of toggle_sidebar()). (#709) Improvements - Closed quarto-dev/quarto-cli#6081: {bslib}'s components (e.g., card(), sidebar(), etc.) now work more sensibly in Quarto docs. (#664) - Closed #672: sidebar() gains gap and padding arguments to control the vertical gap between items in the sidebar and the padding around the sidebar's content. (#725) Bug fixes - Closed #636: Outputs in sidebars now work as expected when an initially-closed sidebar is opened. (#624) - Closed #640: accordion() no longer errors when an id isn't supplied inside a Shiny session context. (#646) - Closed #639: nav_panel()'s icon argument now supports generic HTML(), meaning that things like bsicons::bs_icon() and fontawesome::fa() can be used as values. (#645) - Light-styled buttons in bslib-provided Bootswatch themes are now consistent with their design in Bootswatch. Previously, they were inadvertently styled similarly to secondary buttons. (#687) - Closed #727: layout_column_wrap() now enforces equal column widths by avoiding layout issues caused by grid container overflow. (#729) Changes in version 0.5.0 (2023-06-09) This significant release focuses on making dashboards with filling/responsive layouts easier. See the new Getting Started with Dashboards article to learn more. It also includes new components (accordion()) as well as many improvements and bug fixes for existing features and components. {bslib}'s dashboarding features are still experimental at this point, but this release represents a significant step towards being our recommended way to create Shiny dashboards. Breaking changes / improvements - card_body() now provides the same behavior as card_body_fill() (i.e., it is both a fillable container and fill item) by default. And, now, since card_body() can do everything card_body_fill() can do, card_body_fill() has been deprecated. The main benefit of this change is that card(full_screen = TRUE, ...) with output(s) passed to ... "just works" in an intuitive way. To revert to the previous behavior, set fillable = FALSE and fill = FALSE in calls to card_body() and set wrapper = function(x) card_body(x, fillable = FALSE, fill = FALSE) in calls to card(). (#498) - Closed #375: margin-top is no longer included on header tags that aren't created via pandoc. If this negatively impacts spacing above headers, consider adding a suitable utility class (for example, change shiny::titlePanel("My title") to tagAppendAttributes(titlePanel("My title"), class = "mt-3", .selector = "h2")). (#396) - page_fill() (now called page_fillable()) had several breaking changes (listed below) to better accommodate filling layouts. If this breaks existing behavior, consider using shiny::fillPage(theme = bslib::bs_theme(), ...) instead of page_fill(). - page_fill() now produces a tag with display:flex (instead of display:block). - page_fill() no longer fills the windows height on mobile (i.e., narrow screens) by default (set fillable_mobile = TRUE to restore the old behavior). - page_fill() now adds padding and gap by default, set padding = 0 and gap = 0 to restore the old behavior. - page_navbar() (and also shiny::navbarPage() with theme = bs_theme()) had a couple breaking changes: - The container of each page is now display:flex (instead of display:block). If this breaks existing behavior, set page_navbar()'s fillable argument to FALSE. - header and footer is no longer wrapped in an additional shiny::fluidRow() container. If this breaks existing behavior, consider wrapping the header and footer value(s) with shiny::fluidRow()). (#479) - layout_column_wrap()'s fill argument now controls whether or not the layout container is allowed to grow/shrink to fit a fillable container (e.g., page_fillable()). It also gains a new fillable argument for controlling whether UI elements are allowed to fill their row height. This is more consistent with the meaning of fill in other functions, like card(), card_body(), layout_sidebar(), etc. (#498) - Defaults for the following Bootstrap 5 Sass variables were changed to null: $accordion-button-active-bg, $accordion-button-active-color, and $accordion-icon-active-color. To restore the old behavior, do bs_add_variables(theme, "accordion-button-active-bg" = "tint-color($component-active-bg, 90%)", "accordion-button-active-color" = "shade-color($primary, 10%)", "accordion-icon-active-color" = "$accordion-button-active-color", .where = "declarations"). (#475) New features - Added page_sidebar(), for easy dashboard creation. (#588) - Added a sidebar() API for creating sidebar layouts in various contexts. See the article to learn more. (#479) - Added layout_columns(), for responsive column-based grid layouts. (#587) - Adds a new accordion() API. See help(accordion) for examples and details. Note also accordion() is designed to work well inside a sidebar(). (#475) - page_navbar(), navset_card_tab(), and navset_card_pill() gain a sidebar argument for putting a sidebar() on every page/tab/pill. (#479) - page_navbar() gains a fillable argument to make the content of particular page(s) fit the window/card. (#479) - page_fillable() (aka, page_fill()) is now considered a fillable container, meaning that fill items like card(), layout_column_wrap(), and layout_sidebar() now grow/shrink to fit the window's height when they appear as a direct child of page_fillable(). (#479) - page_navbar() and page_fillable() gain fillable_mobile arguments to control whether the page should grow/shrink to fit the viewport on mobile. (#479) - card(), value_box(), and card_image() gain max_height/min_height and fill arguments. (#498) - card_body() gains a padding argument. (#587) - Added new as_fill(), as_fillable(), as_fill_carrier(), is_fill(), and is_fillable() for testing and coercing potential to fill. (#498) Bug fixes - Closed #558: nested cards with fullscreen = TRUE now correctly and individually expand to fill the window. Tab focus behavior while in full screen mode has also been improved. (#557) - Closed #573: Improved styling when a dynamic result is supplied to value_box()'s title/value (e.g., value_box("Dynamic value", uiOutput("value"))). (#605) Deprecations - card_body_fill() has been deprecated in favor of card_body(). (#498) - page_fill() has been deprecated in favor of page_fillable(). (#498) - nav() has been deprecated in favor of nav_panel() and nav_content() in favor of nav_panel_hidden(). (#476) - The navs_*() family of functions have been deprecated in favor of navset_*() (#476): - navs_tab() is now navset_tab() - navs_pill() is now navset_pill() - navs_pill_list() is now navset_pill_list() - navs_bar() is now navset_bar() - navs_tab_card() and navs_pill_card() are now navset_card_tab() and navset_card_pill(), respectively. Changes in version 0.4.2 (2022-12-16) Potentially breaking changes - Upgraded Bootstrap 5 (i.e., bs_theme(version = 5)) from 5.1.3 to 5.2.2. (#438, #455) New features - Adds a new card() API as well as value_box() and layout_column_wrap(). To learn more about this new functionality, refer to these new pkgdown articles: - https://rstudio.github.io/bslib/articles/cards.html - https://rstudio.github.io/bslib/articles/value-boxes.html - https://rstudio.github.io/bslib/articles/column-layout.html Changes in version 0.4.1 (2022-11-02) Bug Fixes - Closed #458. This release {bslib} now requires {memoise} 2.0.1 or above. Changes in version 0.4.0 (2022-07-16) Breaking changes - bs_theme() now defaults to version = 5 (i.e., Bootstrap 5). If this change happens to break an existing app, consider specifying bs_theme(version = 4) to revert the change in the Bootstrap version. (#374) - The default coloring on some Bootswatch 4+ theme's .navbar-default/.navbar-inverse class has changed slightly to better match their Bootswatch 3 coloring. Also, since this coloring is now based solely on $navbar-* variables, Bootswatch themes now work better in combination with custom $navbar-* values (e.g., bs_theme("navbar-bg" = ...) can be used to provide the background color, and foreground colors will automatically contrast appropriately). (#392) New features - Upgraded Bootstrap 5 (i.e., bs_theme(version = 5)) from 5.1.0 to 5.1.3 (#378) - Closed #369: bs_dependency_defer() now memoises func (by default), reducing the time required to render multiple instances of the same dynamically themable widget. (#405) Bug fixes - Closed #393: Bootstrap 5's $form-check-label-* variables now work as expected with shiny::radioButtons(), shiny::checkboxInput(), and shiny::checkboxGroupInput(). (#395) - Closed #382: Various fixes for using shiny::checkboxInput(), shiny::checkboxGroupInput(), and shiny::radioButton() with bs_theme(version = 5, bootswatch = "sketchy"). (#385) - Closed #377: make sure shiny::tabsetPanel(type = "hidden") (i.e., bslib::navs_hidden()) stays hidden when used with bs_theme(). (#379) - Closed #424: fixed an issue with nav_menu() appearing first in a navs_*() container with Bootstrap 4+. - Closed #431: Bootstrap 5 navbars no longer have an unwanted "Toggle Navigation" label when collapsed. (#432) - Closed #400: nav_menu(align="right") now works with Bootstrap 5. (#401) - Closed #390: using bs_theme(bootswatch = "paper", version = 5) or bs_theme(bootswatch = "readable", version = 5) no longer errors. (#391) Changes in version 0.3.1 (2021-10-06) New features - Upgraded Bootstrap 5 (i.e., bs_theme(version = 5)) from 5.0.2 to 5.1.0 (#365) Bug fixes - Closed rstudio/shiny#3519: nav_menu() (i.e., shiny::navbarMenu()) wasn't producing an .active class on it's .dropdown container properly. (#372) Changes in version 0.3.0 (2021-09-02) Breaking changes - Closed rstudio/rmarkdown#2154: {magrittr}'s pipe operator (%>%) is no longer re-exported by {bslib}. Either library(magrittr) to make %>% available and/or use use R 4.1's pipe operator (|>). New features - Closed #82: Added support for Bootstrap 5 (via bs_theme(version = 5)). Bootstrap 4 remains the default in this release, but the next release, the default will likely change to Bootstrap 5. Bug fixes - Closed #6: rmarkdown's .tabset-fade class now works with Bootstrap 4+ since legacy use of .nav .fade is now officially supported in Bootstrap 4+. (#325) Changes in version 0.2.5.1 (2021-05-18) Small patch release to fix failing test on Solaris. Changes in version 0.2.5 (2021-05-12) New features and improvements - Closed #251: New bs_theme() options (navbar-bg, navbar-light-bg, and navbar-dark-bg) for more easily customizing the navbar's background (and foreground) color (#253, #271). - Closed #281: New bs_theme() argument (font_scale) for easier scaling of the base font size (#288). - Closed #256 and #282: Font file importers (font_google(), font_link(), and font_face()) are now re-exported from the {sass} package. As a result, they may now be used with any Sass variable (e.g., bs_theme("input-font-family" = font_google("Pacifico"))) as well as inside Rmd yaml without !expr (e.g., input-font-family: google: Pacifico -- see #256 for more details). A new font_collection() function was also added for a more convenient way to specify font fallbacks (#291). - Closed #255: bs_themer() now emits sensible yaml front matter when used within an Rmd document (#288). - Closed #227: bs_themer() now overlays a spinner during Sass compilation (#243). - Closed #278: {bslib} now includes rmarkdown::html_document templates demonstrating example usage with {bslib} and {thematic} (#288). - Closed #231: Upgraded from Bootstrap 4.5.3 to 4.6.0 (#254). - Closed #237:

tags now have border-left/padding styles with version = 4 (to mirror the version = 3 behavior) (#239). - Closed #279: Warnings about low color contrasts are now suppressed by default, unless shiny::devmode() is enabled. To enable/disable these warnings, set the new options(bslib.color_contrast_warnings = ) to TRUE/FALSE (#287). - bs_theme_dependencies() now includes Sass source maps when shiny::devmode() is enabled (#312). - Added new bs_add_functions()/bs_add_mixins() and deprecated bs_add_declarations() to reflect sass::sass_layer()'s new ability to place functions before variable defaults. As a result, variable definitions may now use functions defined with bs_add_functions(). (#311) Bug fixes - Closed #236, #230, #242, #187, #215, #250: Addressed various cosmetic issues with CSS (#249). - Closed #289: collapsed navbar toggle now correctly floats to the right (#290). - Closed rstudio/flexdashboard#316: fixed an issue with navbar nav spacing/alignment (#286).
