Prop contracts

Each exported part accepts the underlying native, Base UI, or documented Radix prop contract. Inspect the selected source below for exact generic types.

Troubleshooting

Check behavior before surface.

If the material is missing, confirm the registry-installed shared and component CSS files are imported once.
If interaction differs, preserve this contract: Enter or Space toggles the panel.
If assistive output differs, preserve this semantic foundation: Base UI button and region with expanded-state relationships.
If dark, RTL, or reduced-motion behavior is missing, verify the nearest theme, direction, and media-query boundaries rather than adding page-local overrides.
