Usage

When to use

Use it to clarify state, metadata, content hierarchy, or loading without creating a new workflow.
Pair it with semantic content so visual treatment never becomes the only source of meaning.

Implementation notes

Stylesheet Import @duskmoon-dev/components/styles.css once in the app or docs shell.

State Start with default props for static examples, then switch to controlled props when state must be shared.

Theme The preview inherits the active DuskMoon data-theme value from the docs layout.

Features

Visual hierarchy

Focuses on status, metadata, empty/loading states, or content grouping without owning application state.

Theme integration

Uses DuskMoon tokens so the component follows the active docs theme.

Primary API surface

Collapse is most often configured through `items`, `activeKey`, `defaultActiveKey`, `onChange`.

Covered behavior

Renders item labels with DuskMoon collapse classes

Feature Demos

Feature demos are authored for the component page, then supplemented with behavior scenarios from the component test coverage.
