Hey HMcCoy! It's a little piece of JavaScript which is used to make those menus work. If you want to use it, just chuck the following into your wiki's common.js: importScriptPage('ShowHide/code.js', 'dev'); Alternatively, there is a way to do this with the basic MediaWiki functionality which doesn't rely on JS and which is generally preferable (I only used the JS option because Liquoritz, who I was designing the template for, preferred the opening animation). To use it, change the class called "collapsible" to "mw-collapsible" and "collapsed" to "mw-collapsed", and then use the attributes data-expandtext="..." data-collapsetext="..." to define what you want the open/close buttons to say respectively (obviously replacing the ... with the text you want).

If you need any more help, feel free to give me a shout!
