We are planning to use the groups more often.
Now we have categories 2 layers deep.
Is it possible to add specified groups categories to the second layer ?
Example:
Maincatagory: Marketing
subcategory: Search engine optimization
add a (closed) group to the subcategory: Search engine optimization: **SEO Expert group**

Sure, it’s possible through category permissions in the Security tab
**Marketing** \> parent category, “everyone” can `Create / Reply / See`
**Search engine optimization** \> child category, “SEO expert group” can `Create / Reply / See` (this means that “everyone” can’t see the subcategory at all, unless you set “everyone” to `See` or to `Reply / See`

Yes, i know that, but what if want everyone to see the **Search engine optimization** group and have a special group under **Search engine optimization**?
And that group is the SEO expert group

You mean **SEO expert group** I think.
It doesn’t matter, the category permissions are superior to everything, so even if a group is set to be seen by “everyone”, “everyone” can only see the public topics, not those of restricted categories.

It is not possible to configure more than one level of sub-categories, our structure is `parent category > child category`.

We use tags instead of sub-sub-categories, see

안녕하세요, discourse
카테고리의 모든 하위 카테고리(slug-1 slug-2 slug-3 slug-4)에 “level-3” 그룹을 추가하고 싶은데,
어떤 콘솔 명령을 사용해야 하나요?
감사합니다! 🙂
