Controlled Collapsible

A React controlled collapsible using useState with open and onOpenChange props for external state management and status display with shadcn/ui

Control means power—external state enables coordination. This React controlled collapsible uses useState with open and onOpenChange props managing expansion state externally. Built with shadcn/ui and Radix UI featuring visible Status indicator showing Open or Closed state and programmatic control enabling conditional expansion, multi-collapsible coordination, or state persistence. The controlled pattern lets you respond to state changes, integrate with forms, sync with URL params—perfect for complex UIs, coordinated interfaces, analytics tracking, or anywhere collapsible state needs external management beyond component-internal toggling.
