Card surface
card gives the disclosure an outlined card container with inset header and content on web and Android. On iOS the default Collapsible already renders as the inset-grouped card, so card changes nothing there (a documented no-op).

Props

12 props on CollapsibleProps, grouped as they are declared in source. Required props are marked *.

Description
Props
12 props
title
string
–
The default trigger label text.
description
string
–
The muted secondary line under the title in the default trigger anatomy (ignored when a custom trigger is given, which owns its own anatomy).
trigger
ReactNode
–
A custom trigger node; if provided, it renders as the pressable's content instead of the title text (the chevron still renders alongside).
card
boolean
false
Card surface: wraps the disclosure in an outlined card container with inset header and content (web/Android). On iOS the default Collapsible already renders as the inset-grouped card, so card is a no-op there.
reference
boolean
false
The reference-sheet card (a component page's sub-component props): the card corner on a hairline over the card fill, a 46 px toggle with the title in 600 14 and the description inline after it in the mono meta ink, and the content flush to the card's edges, for a reference attached DataTable (web/Android). On iOS the default Collapsible already renders as the inset-grouped card, so reference changes nothing there.
children *
ReactNode
–
The collapsible content. A string renders in the skin's content type; a ReactNode renders as-is.
open
boolean
false
Controlled open state. Pair with onOpenChange. Omit for uncontrolled.
onOpenChange
(open: boolean) => void
–
Called with the next open state whenever the header toggles.
defaultOpen
boolean
false
Initial open state for the uncontrolled case (read once, default false).
disabled
boolean
false
A disabled header does not toggle and reads dimmed.
testID
string
–
E2E hook forwarded to the root element.
style
LayoutStyle
–
Composition within a parent only, never a restyle hook and never a width: the parent layout container provides the bounds.

Usage

<Collapsible title="Shipping details">
Free 2-day shipping on orders over $50. Delivery in 3 to 5 business days otherwise.
</Collapsible>
Closed by default; pass defaultOpen to start open. Open state is controlled (open + onOpenChange) or uncontrolled (defaultOpen). A description adds a muted secondary line under the title; card wraps the disclosure in an outlined card surface on web and Android (on iOS the default look already is the inset-grouped card, so card is a no-op there). For a set of related, peer sections, reach for an Accordion (a group of these); Collapsible is the standalone primitive.
