# Benefits of collapsing or expanding element groups in Diagram elements

Collapsing or expanding clustered engine elements makes complicated diagrams simpler, as the individual items can be viewed only when needed.

You can collapse and expand clustered engine elements, such as a Firewall Cluster, an IPS Cluster, or a Layer 2 Firewall Cluster. You can also collapse and expand groups of elements (any group of elements you select) to hide the individual nodes or elements. You can collapse and expand clusters and element groups while viewing and editing diagrams.
