Hi. I want to build a knowledge base with topics and subtopics. I want the first three subtopics to be displayed, and then a link "see all categories" showing all subtopics in that category. I cannot seem to figure out how to do this.

I understand I can use the /expand shortcut, but then all my topics will be hidden (only "see all categories" will be displayed). And when mixing the two together the formatting won't match.

Please advice!
