Detailed Description

A collapsible section widget for use in a QSplitter.

This widget displays a clickable header that toggles the visibility of the content area. When collapsed, the widget shrinks to just the header height. When expanded, it can be resized via the parent splitter. Multiple CollapsibleSection widgets can be independently expanded or collapsed.
