Layton Wiki (http://layton.wikia.com/wiki/Template:Navbox) has drop-down menus in its sidebar (namely under "Navigation") that I'd like on my Wiki, subject to customization, of course, (i.e., ofc I want to customize the page titles in the drop-down menu and where they link on my Wiki as my Wiki has significantly different content to Layton Wiki). How would I do this? I assume it would involve editing MediaWiki extension pages like MediaWiki:Sidebar.
