Its possible to assign a group the moderating power on just one category, However be aware that this will also include other moderation powers such as Forking, Closing and Moving topics.
Suggested Topics Widget
I dragged and dropped the Suggested Topics HTML widget into the global footer but it is not showing up. I rebuilt and reloaded the site and it is the latest version of Nodebb v.1.16.2.
Also, how can I make it appear on only certain categories and topics and not others?
All the Best,
I have same question.
