I am creating a website in Wordpress and am encountering a small problem. This site utilizes a somewhat complex marking system for the reason that you will find multiple kinds of tags, for example CLIENTS, COLOR, THEME, and Extra supplies.
Automatically, all tags live inside the same group. Can there be in whatever way to arrange tags into groups that may later be known as by Wordpress? Much like the way the groups work?
Edit: Possibly there's a method to make this happen using custom fields? My problem is that custom fields fail to work in the same manner tags do, for the reason that you cannot browse posts that share exactly the same value.
