rstudio/bslib v0.5.1 on GitHub

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)

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)

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)
