Collapsibles are simple widgets that allow you to expand or collapse content when tapped and are useful in mobile to provide a compact presentation of content.

To add a Collapsible to your app, choose the Collapsible icon in the Toolbar, then position it on the Design Screen. Use the Property Editor to set the properties you need.

Children can be added at Design Time by dragging them on to the Collapsible control in the Design Screen. At runtime, use the addChild() function.
