Forum:How to do a retractable template

I have seen that Wikipedia and some wikis make use of retractable boxes with a show/hide button. I thought it would be useful to adopt to include non-canon information in the wikis. However the source of those templates is too complex and I still haven't figured out the commands and syntax that can make a simple retractable "box" or "frame" with text in it, viewable at will. Can you redirect me to some relevant resource? MoffRebusMy Talk 16:44, 28 August 2009 (UTC)
