# View Hierachy

As an administrator, the user can access the CA Hierarchy user interface, which presents a hierarchical view of CA Certificates, including both Root and Sub CA certificates. This interface outlines the certificate chain for each sub-hierarchy in a tree structure, with the Root level on the left-most side.

By clicking on a particular CA certificate, the Administrator can

* View certificate details
* Delete certificates 
* Export certificates

Users can easily filter for matching CA names using the "Search" field above the CA hierarchy.

Users can delete CA certificates by clicking "Delete" in the detail view, followed by a confirmation dialog.
