Only posts support the use of categories and tags. Categories apply to posts in order, resulting in a hierarchy of classifications and sub-classifications. Tags are all defined on the same hierarchical level so the order in which they appear is not important.
If you want to apply multiple category hierarchies, use a list of names instead of a single name. If Hexo sees any categories defined this way on a post, it will treat each category for that post as its own independent hierarchy.
