ZdsExpandable class

A component that can be collapsed and uncollapsed.

This is typically used with long Text widgets, where their length might complicate navigation.

When collapsed, the component will take the height of minHeight. If the child's height does not exceed minHeight, then no button to collapse/expand the widget will be shown.
