Navigation Pane's Context Menu
The Navigation Pane’s context menu can be invoked by clicking a special sign within the overflow panel. This menu enables end-users to change the number of visible group headers, and toggle the visibility of groups. The menu’s structure is shown in the image below.
To prohibit end-user group customization, disable the NavBar control’s OptionsView.NavigationPane.AllowCustomizing option, to remove the “Add or Remove Buttons” item from the context menu.
