Gets or sets whether each group in the collapsed Navigation Pane can have a selected item. This is a dependency property.
true, if each group in the collapsed Navigation Pane can have a selected item; otherwise, false.
By default, when the EachCollapsedGroupHasSelectedItem property is set to false, only one item can be selected among all groups in the collapsed Navigation Pane at a time. Selecting an item in a group deselects the previously selected item, even if it is contained in another group. Set the EachCollapsedGroupHasSelectedItem property to true to allow each group in the collapsed Navigation Pane to have a selected item. In this case, several items can be simultaneously selected in distinct groups, but not in the same group.
To obtain an item selected in a particular group or the currently active group in the collapsed Navigation Pane, use the NavBarGroup.CollapsedNavPaneSelectedItem and NavigationPaneView.ActiveGroupCollapsedNavPaneSelectedItem properties, respectively.
See the NavBarGroup.CollapsedNavPaneItems property to learn more about items displayed in the collapsed Navigation Pane.
