Hi, sorry to bother you. I just made my own MediaWiki site for an anime series (migrated from Fandom/Wikia) recently and really like the sidebar you have here. I was wondering how you were able to add it. I've tried using this extension: https://www.mediawiki.org/wiki/Extension:TreeAndMenu but I can't figure out how to get the menu in the sidebar. Would appreciate any help. Thanks.
