The Group Hierarchy or “Navigation” menu provides a hierarchy of the groups and their child groups which the user may access. The Group Hierarchy also displays a count of the devices contained in each group. At the base level of the Hierarchy, the menu provides the user with access to the Search and Settings features of the application. The View Group Summary button will be enabled and allow the user to view the Group Summary page for any group containing devices. The currently selected group is displayed on the navigation header and all of its child groups and their device counts are displayed in the hierarchy list.
