I've been trying to make heads or tails on creating fairly simple 3 level category index or menu. I've tried implementing various code from this forum and links elsewhere but they don't seem to work for me. What I'm basically looking to do is this type of design:
topic -> list of articles -> article
with each click opening up the article or article list in the main part of the page. So far all my attempts have been messy as all hell. Any help would be very much appreciated!
