Add a sub-category to a sub-category

AI-generated summary

In a support discussion titled ‘Add a sub-category to a sub-category,’ Yves_Lauzin asks whether it’s possible to create a sub-category under another sub-category. Thomas_G replies that Discourse only officially supports categories and subcategories, suggesting tags as an alternative for deeper classification. Yves_Lauzin seeks clarification on tags, prompting Jonathan5 to share a meta post explaining how sub-subcategories can technically be enabled. Thomas_G follows up with a guide on Discourse tags. tshenry advises against sub-subcategories, recommending tags as the better solution for additional classification, but confirms they can be enabled via the linked meta post. Cozdabuch counters that in complex setups — such as multiple business workgroups sharing one Discourse instance — sub-subcategories would be more practical than tags. They explain that forcing a sub-subcategory into a new top-level category disrupts site structure and complicates management. Overall, while sub-subcategories are not officially supported and discouraged for most use cases, they can be enabled via configuration, and tags remain the recommended alternative for additional categorization.

Hello,

Is there a way to add a sub-cat to a sub-cat ?
I mean a sub-cat with a ‘parent’ sub-category ?

It seems it’s not possible ?

thank you for help.

Hello!

AFAIK, there are only categories and subcategories. Sub-subcategories do not exist. Tags might be the best solution for that.

Thank you , what do you mean with ‘tags’ ?

Generally speaking sub-sub-categories are not a recommended organizational structure. Tags are almost always the better option when you need additional classification beyond the single sub-category level. With that set, sub-sub-categories do exist and can be enabled using the steps in this post:

Taylor, in some cases (multiple business working groups within the same discourse instance) sub-subcategory capability would be much more preferable to tags.

There is a main common space, but each work group gets a category that has subs. With some subs, an extra sub is needed forcing a sub into a new master category which is inconvenient for managing/sorting the site’s structure..
