Forum:How to add a collapse option to a character Infobox

Hello,

I was allowed to copy the Avatar Wiki character infobox and I am wondering how to collapse a section to give content on the page room to stretch. I mainly edit in Monobook so I usually forgot how squished everything is in Oasis until I check. If you don't have enough intro content to push other information and headers downward, you basically get a bad viewing of the page.

I want to put "Physical description" and "Personal and Chronological information" under a show more option. The show/hide js is already on the wiki.
