Package Exports

@accessible/disclosure

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@accessible/disclosure) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

open	`boolean`	`undefined`	No	You can control the open/closed state of the disclosure with this prop. When it isn't undefined, this value will take precedence over any calls to `open()`, `close()`, or `toggle()`.
onChange	`(open: boolean) => void`	`undefined`	No	This callback is invoked any time the `open` state of the disclosure changes.
id	`string`	`undefined`	No	By default this component creates a unique id for you, as it is required for certain aria attributes. Supplying an id here overrides the auto id feature.
