Instead of having all categories appear in one category tree, Cumulus provides multiple master categories, each with its own category tree: Cumulus lets you create your own master categories with their own individual category trees.
To create a new master category:
1. Click on the entry for the catalog in which you want to have the new master category.
2. Select Metadata > New Master Category. The New Master Category dialog is displayed. Enter a name for the new master category and press Enter.
You can rename or delete such a category just as any other category.
