I am having a problem with the subnav on my site. I would like to have each div at the top of the doc expand when clicked and then completely collapse and reexpand the correct div when any other subnav link is clicked. Right now the divs are not collapsing.

I would appreciate any help anyone can give. Maybe an If/Else solution? I dont know enough about Jquery to figure it out right now.
