API Reference

Prop	Type	Default	Description
openAlertDialog	boolean	-	Controlled open state. Pair with `onOpenChange`.
defaultOpenAlertDialog	boolean	false	Open state on first render when uncontrolled.
onOpenChangeAlertDialog	(open: boolean) => void	-	Called when the open state changes.
renderAlertDialogTrigger	React.ReactElement	-	Replaces the default trigger button with your own element, e.g. `render={<Button>Open</Button>}`. Base UI merges props onto it.
