I would have liked to know more about topic tags:
1 – How to create topic tags and restrict their use to certain groups only (moderators and administrators).
2 – How to create specific labels for a specific forum? I would like to create an Ideas / Suggestions category and create the following labels:
In the study.
Planned.
In progress.
Implemented.
Rejected / Not retained.
3 – Finally, how to define a different color for each label?
To create tags and set up visibility/use restrictions have a look at this guide below
Once you have followed the guide on creating a tag group all’s you need do is go the ‘Idea / suggestions’ category settings and add the tag group here (red arrow) and press save
