rstudio/bslib v0.12.0 on GitHub

New features

Added offcanvas() to create Bootstrap offcanvas panels that slide in from an edge of the viewport. Panels can be revealed by a trigger element in the UI or controlled from the server with show_offcanvas(), hide_offcanvas(), and toggle_offcanvas(). (#1328)

layout_columns() and layout_column_wrap() now describe their CSS length inputs with concrete examples. (@LeonidasZhak #1300)

Fixed dynamically-rendered outputs (e.g. uiOutput()) failing to render inside a title-less popover() or tooltip(), caused by an upstream Shiny change. A temporary CSS workaround restores rendering. (#1326)
Fixed label-to-options spacing on shiny::radioButtons() and shiny::checkboxGroupInput() in Bootstrap 5, where a Shiny rule was overriding the bslib fix. (#1308)
Fixed the resize handle indicator position for position = "right" sidebars, which now correctly appears at the inner boundary of the sidebar handle. (#1322)
Allow users to directly grab the sidebar handle to resize the sidebar. (#1331)
