>I am looking for a control - Outlook style Navigation bar which has Groups within groups.

>Both of these seem to have just Groups with Items (i.e. each item itself cannot be a group) so yu can only have 1 level grouping and not sub-grouping. Perhaps I have missed something ??. These controls , with some additional controls , can be mase to simulate Sub-groups but natively they dont seem to do it.
