About Categories
Group tags into categories, and choose their scope and whether they are mandatory or restricted.
Updated on 7 October 2026
A category groups tags of the same kind. For example, the tags "France" and "Belgium" belong to the category "Country". Tags without a category are called hashtags.
Create a category
-
Click your profile picture in the top right corner, then click "Settings".
-
In the menu on the left, open "General" and click "Categories".
-
Click "Add a category".
-
Write the name of the category in each language.
-
Choose the settings of the category, then click "Create":
-
Scope: "Available in all spaces", or "Limited to specific spaces".
-
Mandatory: "Require at least one tag of this category." An article must then have at least one tag of the category.
-
Restricted: "Users cannot create new tags." Only administrators add tags to the category.
-
The Categories page lists the categories with their spaces, their settings and their number of tags. Use "Actions" to reorder the categories or to download tag statistics.
In categories that are not restricted, contributors can create new tags when they tag an article. Administrators and coordinators keep the list of tags clean: see Gardening tags.
Tags are shared: everyone sees the tags that other people add.
Our advice
-
Keep a small number of categories: about ten is a maximum for most platforms.
-
Create categories that work across teams.
-
Restrict the categories where the list of tags must stay fixed.
-
Avoid mandatory categories: they can discourage people from contributing.
-
Give categories short and clear names.
Examples of useful categories: type of content (news, report, study, benchmark), language, department (finance, legal, communication), organisation and country.
