I like the way the left hand nav operates on the Telerik Demo pages (E.g. http://demos.telerik.com/aspnet-ajax/label/overview/defaultcs.aspx). It looks like its built with a SearchBox at the top, a ToggleButton to switch between the currently selected Control and the 'All Controls' menu. Is there a source code example of this anywhere? I like the way the menu slides left and right based on the Toggle Button and wanted to know how this was achieved.
