Admin Forum:Collapsible Feature How-To?

I have ANOTHER question, and I need help. I created this template on the Screenzilla Wiki, and I want a certain part of the template to be collapsible (under a title). Here's the code for the section I wanted to collapse:

! colspan="2" style="text-align:center; color:black; background:#6C93B1;" font-size:larger;"|Full Video
 * colspan="2" style="text-align:center; padding:0; background:;"| [[File:|258px]]
 * }
 * }
 * }

I want everything below the title "Full Video" to automatically be collapsed, but allow readers to open and close it at will. I could really use some help, because the video takes up a lot of space. Thanks in advance!
