Each example has a page where you can find the complete information on it: description, main features, runtime, source code, and other.
Examples are grouped usually per main component they are about, such as grid, tree, panel, or by a more general area, as architecture, state, data, etc.
The navigation tree on the left is stateful what means that the folders start expanded or collapsed exactly as you left them off at your last visit.
