The ‘Categories’ tab is where you manage categories (and sub-categories) for each collection in your site.
Categories can be used to sort or group items in your collection.
You must create at least one category for each collection you wish to post to. You can duplicate category name in different collections and they will remain distinct. For example, if you have a category called
Habitat in your Elephants collection you can also have a category called
Habitat in your Hyenas collection. The two categories will have distinct ID’s in the database and items will not be confused between the two collections.
