Collapsible

Component 8

About

A minimal show/hide primitive built on Base UI's Collapsible. A trigger toggles a height-animated panel — perfect for read-more text, FAQ rows, nested groups and expandable log output. Controlled or uncontrolled via open / defaultOpen, with data-panel-open styling hooks. Ships Collapsible, CollapsibleTrigger and CollapsiblePanel (also exported as CollapsibleContent).

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Collapsible to your project and fits it to your theme.
