Measured entry

shadcn-collapsible

accordionunclassified

A client-side React wrapper around Radix UI's collapsible root, trigger, and content primitives. It ships as copy-in source from the shadcn registry, adds data-slot hooks, and depends on the radix-ui package. Styling and layout remain the consuming application's responsibility.

Verdict

A dependable, intentionally thin disclosure primitive that builds and mounts cleanly without provider wiring. Choose it when Radix behavior plus local styling is the goal, but address narrow-screen overflow and do not mistake it for a complete accordion.

Use it if

  • You need an accessible disclosure for optional details, filters, or compact supporting content.
  • Your React app already uses Radix UI or is comfortable owning styles around unstyled primitives.
  • You want source-level control over a very small wrapper instead of a packaged visual component.

Skip it if

  • You need a full accordion with coordinated multiple sections and exclusive-open behavior.
  • You expect finished visuals, spacing, icons, or motion without adding application styles.
  • Your narrow layout cannot accommodate content that may overflow unless you revise the demo sizing and content wrapping.

In a non-shadcn React project, install radix-ui, copy the wrapper module, and ensure the app supports client components and the source's TypeScript JSX syntax. Add your own trigger, content, focus, spacing, overflow, and optional motion styles.
