The item that is currently selected in the current sub-menu.
The SelectedItem property specifies the item that is currently selected in the current sub-menu.
If the HamburgerSubMenu.IsStandaloneSelectionItemMode property is set to true, selecting an item in the current sub-menu does not discard the selection in the main menu. If this feature is enabled, use the HamburgerMenu.SelectedItem and SelectedItem properties to get the item selected in the main menu and the current sub-menu, respectively.
