Hi everyone, I want to enforce a rule in my Discourse forum where, for a specific category only, users must attach a particular tag when creating a topic. Users can attach any number of tags, but one specific tag must be present; otherwise, the topic creation should be blocked with an error message…

How to enforce a required tag for topic creation in a specific category via theme JS (Blackout theme)?
