Navigation Hierarchy 

The navigation hierarchy is a structure of navigation nodes. It can be maintained in a tree, map, list or array structure or any other structure that organizes the nodes correctly. The following diagram shows an example of a navigation hierarchy using a tree structure and based on portal roles:

 

 

The diagram shows the different types of nodes:

·        Valid/Visible: For these nodes, navigation iViews display a link to the content. This type of node is located under one of the initial nodes in the navigation hierarchy.

·        Valid/Invisible:  For these nodes, navigation iViews do not display a link to the content, but the user is still allowed to view the content. The user can access the content by supplying the correct navigation URL or by clicking a link supplied with a content iView.

A navigation node is valid/invisible when:

¡        It is located under a role but not under an initial node in the navigation hierarchy.

¡        Its invisible attribute is set to true.

·        Invalid: The user is not allowed to access the content for this node.
