About
In Content Hubs, galleries are created as categories in the Rich Media Content Management System.
Once created, galleries appear in the Content Hub navigation bar. You can manage whether galleries appear in navigation using the Navigation module.
To create a gallery, see Create categories in the Rich Media CMS. Categories created in the Rich Media CMS appear as galleries in Content Hub.

Although galleries are created in the Rich Media CMS, you can create sub-galleries directly in Content Hub. For more information, see Create a sub-gallery.
If you don’t have access to the Rich Media CMS, contact your administrator for help.
