Connect your library with MCPui/accordionUsage
Get this component from a saved library export or the connected CLI. The imports below refer to local files installed in your app.
Import styles/components.css, then styles/theme.css once. Wrap your app in ThemeScope from components/ui/utils so typography, focus and overlays share the theme. The installation guide covers runtime dependencies and React/Next.js setup.
import { Accordion } from './components/ui/accordion';
<Accordion items={[{value:"ownership",title:"Do I own the code?",content:"Yes. Export it and use it in your own project."},{value:"runtime",title:"Does it need a server?",content:"The exported components run independently."}]}/>Design system
This component consumes your semantic colors, spacing, typography and shape tokens. Import the compiled styles and your theme once as described in Export.
Behavior and accessibility
- Provide meaningful labels for interactive controls.
- Connect action callbacks to your application logic.
- Verify keyboard navigation and contrast in your application.
Status: experimental during early access. Sample previews do not send emails, process payments or upload files to a service.
