ViewApp custom navigation rules

The following list describes some restrictions and behaviors when building a custom navigation model for a ViewApp.

• Add a new navigation item

  You cannot add a custom navigation item at the same level of the navigation hierarchy that contains a sibling navigation item with the same name.

• Configure a reference to an Assets or Toolbox folder

  When you configure a reference to an Assets or Toolbox folder, the name of the navigation item does not change and can be renamed if the new name does not match an existing sibling navigation item.

  You cannot add a new custom navigation item beneath a navigation item, which references an Assets or Toolbox folder. The Add menu option should be disabled.

• Asset hierarchy root node behavior

  You can select the root node of the asset hierarchy, as viewed from the Template folder of the System Platform IDE, for a reference to include asset nodes. The user can also select any child node in the asset hierarchy for the reference.

• Valid content in the Visualization folder hierarchy

  You can select any folder in the Visualization folder hierarchy, including the root of the tree.

• Removing a Navigation Item

  You can remove a navigation item from the hierarchy. All children items are removed if their parent is removed. A confirmation dialog box appears and requests confirmation that you want to remove the navigation item.
