Help Rabid because he doesn't know much about mediawiki

Ok, I want this page (or rather, the bottom region of it): http://lineriderwiki.byethost8.com/index.php/Main_Page

to look like this: https://iridethelines.forumotion.com/t3743-categories-masterlist

using this: http://en.wikipedia.org/wiki/Template:Hidden_begin

When I just used the syntax detailed on that page it gave me an uncreated page "Template:Hidden_begin" so I went looking for something to put in the page, and found this page: http://en.wikipedia.org/w/index.php?title=Template:Hidden_begin&action=edit

and tried to put that in the page. but then basically the whole page freaked out.

How do I do this lol

nobody? sadface

I'm not good with this kind of stuff

Did you, by any chance, forget to put Template:Hidden_end in there?
Cuz that would definately [censored] up the page.

Other than that, I have no clue.
