Top-Level Navigation iView
The following creates a one- or two-level top-level navigation iView, depending on the value in the NumOfDisplayLevelsproperty of the navigation iView portal component. The page does the following:
· Iterates through the initial nodes.
· Saves the node that is selected.
· After iterating through all the initial nodes, recalls the selected node and iterates through its children.
