Examples

Rendered live from the maintained Storybook story. Lantern stores only the story id and embeds Storybook rather than duplicating the component or its demo.

Sidebar accordion section

Rendered live from Storybook

Open

Storybook must be running for this to load — bun run start:storybook from the monorepo root, or set NEXT_PUBLIC_STORYBOOK_URL to a deployed instance.

Props

The component's public API, read from its TypeScript source. Descriptions come from TSDoc on the prop, so this table cannot drift from the component.

Prop	Type	Default	Description
`title`*	`string`	—	Undocumented — add TSDoc to the prop in the library.
`children`*	`React.ReactNode`	—	Undocumented — add TSDoc to the prop in the library.
`defaultOpen`	`boolean`	`true`	Initial open state when the section manages itself.
`open`	`boolean`	—	Controlled open state. When provided the section stops managing its own state and simply renders what it is told — which is what lets a story pin the collapsed and expanded states as two static snapshots rather than a click-path.
`onOpenChange`	`(open: boolean) => void`	—	Fired with the next open state on every header click.
`className`	`string`	—	Undocumented — add TSDoc to the prop in the library.
