To anyone else stuck with this issue i.e. trying to make wikpidea navbox work here is how it's done.(I have done this recently)

Either import wikpidea script by placing this in your common.js importScriptPage('ShowHide/code.js', 'dev');

Or update your navbox. which is preferable but take a little more work:
 * 1) Wikpidea use a special script we don't need. Replace in the navbox template 'collapsible' with 'mw-collapsible', you can also remove the autocollapse segment(I couldn't find support for it in mediawiki 1.18+ and it's used so rarely that you shouldn't care)
 * 2) Wikipidea script use show/hide, while mediawiki use expand/collapse. To "fix" this see this

Alternatively you can look at our template, where I already done both.

Last you need to adapt your css. The id of mediawiki is diffrent change 'collapsible-button'(or something like that)to 'mw-collapsible-toggle'. Also if you skipped 2 make sure to change width of to balance the button against the vde links so it won't twitch when you click on the expand/collapse.
