There are only categories and sub-categories. There are no sub-sub categories.
On your home page you can click the little hamburger next to the new topic button and add a category. You can then choose a parent category for it.
then how does this forum get 2 sub-categories for certain topics?

现在有一个名为 max_category_nesting 的隐藏设置,可以在 rails 控制台中更改。Sub-sub-categories - #2 by jomaxro 提供了一些提示。
