Hello, there is a sub-category. It would be good to have six features in the sub-category. It would be good to have the option to add sub-category sub-category in multiple categories.

For hosted plans, this is only available for Enterprise plans.
It may be worth thinking instead about whether you can use tags for this purpose. You can use tag groups and require certain tags for a category — and restrict them as well.
In my experience, it’s best to use categories when there is a _functional_ difference: different permissions, different defaults, different auto-close policies, etc., and tags for _topical_ distinctions.

Thank you for the information, there are multiple categories on the site I use, I think it cannot be as a tag.

Hello, I don’t understand this part (enter app rails c SiteSetting.max\_category\_nesting = 3 exit exit) exactly what I need to do, add it and look, nothing happens

I will warn though nesting Subcategories can pose problems with posting a new topic in my xp.
A good option can be to use tags as an Alternative to separate topics.

When you run that command on the Server Root it unlocks changes.
After running and exiting. Refresh page on your forum. Create a category with the Parent Category being the name of your subcategory.
