About ViewApp navigation hierarchical display

AVEVA OMI includes a NavTree app that shows a ViewApp's navigation items arranged in a hierarchical tree. During configuration time in the ViewApp Editor, the NavTree app shows this navigation item hierarchy based on the Model view of object instances. This view represents the navigation model of the ViewApp being edited.

During runtime, users can select the chevron icon next to a navigation item to expand or collapse the tree of navigation items.When an item is selected from the tree, the item's navigation commands are executed and associated content appears in layout panes that meet the command requirements.
