PropTypeDefaultDescription
CollapsibleBitCollapsibleProps—Extends React.ComponentProps<typeof CollapsiblePrimitive.Root> and explicitly declares asChild?: boolean. Supports the Radix root props, including open, defaultOpen, disabled, and onOpenChange. The className is applied to both the outer relative div and the Radix root, with retro added to the root class.
CollapsibleTriggerReact.ComponentProps<typeof CollapsiblePrimitive.CollapsibleTrigger>—Accepts Radix CollapsibleTrigger props, including its button props and className. Adds data-slot="collapsible-trigger" and retro to the class.
CollapsibleContentReact.ComponentProps<typeof CollapsiblePrimitive.CollapsibleContent>—Accepts Radix CollapsibleContent props, including its content props and className. Adds data-slot="collapsible-content" and retro to the class.
Accessibility
- The Radix trigger provides the disclosure control and communicates its expanded state to assistive technology.
- Give each trigger a clear accessible name; the trigger’s children commonly supply its visible label.
- Keep the trigger and its associated content together inside the same Collapsible root.
