Is it possible to create sub-subcategories?


(Courtney) #1

Is it possible to create subcategories within subcategories? For example, can I have a grandparent category, parent subcategory, and child subcategory? If not, is there any alternative to creating a separate instance for each “grandparent”?


Sub Sub Categories?

No, there are only two levels of categories in Discourse.

We’ll combine the 2 levels of categories with tags. It’s not just about taxonomy, it’s also about moderation rights.

Will 3 levels of categorization be possible in the future? My site is about 4 sports, then within each sport, I want a category called “Gear”, and then within “Gear” have the different brands.

I could also do a top level category called Gear, and then have the Gear Companies underneath.

Or just have the Gear companies for each sport listed directly under the sport.

No plans for more than 2 levels of categories. As @jeans noted, adding tags into the mix makes more sense at that point. So use the official tag support built into Discourse.

@codinghorror What would be the technical implications of allowing deeper nesting of categories? I don’t have a specific requirement in mind, just curious. I can see UI concerns, but the data model looks like it could handle chains of parents.

Here a typical case where we need to configure Discourse with 3 levels,
Local Groups - Open Knowledge Forums

the local-groups are in fact the “level zero”, in some cases we also change language (!), as at local-groups/okbr. The main topics are at this level-2, it is ok, but…

The level-3 is important to isolate very distinct topics and/or communities:

  • to isolate official topics. Example: today we use the “official” tag as here, but we need to isolate as local-groups/okbr/oficial,

  • to isolate projects, because they have independent communities and very specific topics. Example: this project was losted in an external category, openspending/gastos-abertos, we need an intersection between openspending and local-groups/okbr and we understand that the second is the priority, so need category local-groups/okbr/prj-gastos-abertos that is a typical “local group project” category.
