You may find that your CI structures contain many items, and this may make the diagram difficult to navigate and clearly understand. You can, however, show or hide specific items on the structure view. This does not remove or modify them, rather just hides them on the diagram.
To modify display filters:
Open the required structure view diagram.
On the Display Filters tree, clear or select the required check boxes.
The relevant Items or Relationship Types are hidden or displayed.
