Category/sub category only with topic with certain tag(s)?

Is it possible to create another category with the name “Music” (or any other name, that’s not the issue), where it only loads topics with the “Tiago” tag?

No, that’s not possible.

@alltiagocom

but I wanted something that allows me to use the banner the same way I can with a category, or using an image at the top.

You can have a banner for a tag page. For example, Contribute > Bug email : https://meta.discourse.org/tags/c/bug/1/email

You can probably customize it with CSS to make it similar to the category banner.

If not with tags, is there a way to achieve something similar? I just don’t to double post.

A subcategory in which only you have permission to create new topics?
