The following example aims to mimic the navigation provided by the Movies & TV app in Windows 10 by using RadPageView in Backstage view mode. In this example, the tabs are positioned on the left part of the control and when the expand/collapse item is clicked the menu will expand/collapse. When the menu is expanded the items will have text when it is collapsed only icons will be displayed. The example also shows how you can create search tab item. When the search item is clicked the menu will expand and a text box will be displayed. You can see the final result in figure 1.
