About
The Categories module defines the root category used by your Kaltura application and controls how media from this and other connected Kaltura applications is surfaced to users.
In Content Hubs or legacy Video Portal, categories appear to users as galleries in the site's navigation menu.
In LMS Extensions or LMS Video integrations, categories are used behind the scenes to support features such as Media Galleries and shared repositories.
Before you start
Before configuring this module, you must create the required categories in the Rich Media Content Management System (Rich Media CMS). See our article Create categories in Rich Media CMS.
Configure
1. Go to your Configuration Management console, locate the Categories module in the left panel, then select it.. You can also navigate to it directly using a link: https://{your_site_URL}/admin/config/tab/categories.
