Hi,
I am not sure whether I get your question correctly. For SlideMenu, it only expand/collpase top level items. In this case, your "Inventory". If your Menu structure is like this:
Code:
Inventory
Sub Menu 1
Item 1
Item 2
....
Sub Menu 2
Item 1
Item 2
....
Orders
Sub Menu X
Item a
Item b
Then clicking Inventory will expand sub menu for Inventory, clicking Orders will expand sub menu for Orders. The behavior for a slide menu can be summarized as:
1. Top level items expand/collapse a sliding pane;
2. Second level items appear inside the sliding panes;
3. Third level and on are displayed as popup menu;
If you wish all level to be sliding panes, you can use a TreeView control instead of a SlideMenu control. You can customize the appearance of a TreeView to look very much like a SlideMenu. The difference is TreeView never displays a popup menu, all levels are expandable/collapsible.
Hope this helps. Please feel free to let us know if you have any more questions.
Thanks!
