Base UI is a library of headless ('unstyled') React components and low-level hooks. You gain complete control over your app's CSS and accessibility features.

import { collapsibleOpenStateMapping as baseMapping } from "../../utils/collapsibleOpenStateMapping.js";
import { transitionStatusMapping } from "../../utils/styleHookMapping.js";
export const collapsibleStyleHookMapping = {
  ...baseMapping,
  ...transitionStatusMapping
};
