I have a bunch of categories which have children categories within them.
Right now, if I try to visit the page for a parent category all it displays is "No topics found". What I'd like to have happen is that if it's a parent category, it would list all of it's children categories, and possibly even nested list with all of the topics in the category (just the title).
Anyone have ideas about how to get started? I don't need the details involved, just an idea of what functions I can use to get the information I want.
