BCollapse Migration ​

Summary ​

Migration notes for BCollapse from BootstrapVue to BootstrapVueNext.

Affected APIs ​

Breaking Change ​

The prop toggle has replaced the prop appear with slightly different semantics. In order to create a collapse that is closed and transitions to open on the initial mount, set visible to false and toggle to true.

The close scoped slot element has been replaced by hide for consistency with the other props and events on this component.

$root instance events bv::collapse::state and bv::toggle::collapse are deprecated.

See Show and Hide shared properties.
