Board Thread:Support Requests - Designing Your Wiki/@comment-9252502-20171222020030/@comment-34000677-20171223154828

To be honest, you would have to develop your own code to create something like FANDOM. FANDOM uses a lot of custom code that integrates MediaWiki within it. The header, footer, chat, discussions, and more have been created by FANDOM to fit its purpose and goal. Even MediaWiki, the platform FANDOM wikis are running off of, has been renovated to match FANDOM's brand, purpose, and goal.

For this reason, there isn't a plugin, theme, or module that matches the FANDOM site because that's their custom coding and personalized user experience. My suggestion is to create a wiki here (where there is more publicity, traffic, SEO, and support), rather than creating it elsewhere where it may be a large workflow and a lot of coding. This will save you a lot of trouble and let you dive right into the features that FANDOM has to offer. :D

Good luck!
