74964 Expand CSS Menu

On one of our sites, a new design calls for a modification of Dave Lindquist's ([login to view URL]) CSS-based menus. A demo of our page can be found at [login to view URL] The menu is working fine but we'd like the ability for the menu to be pre-expanded on select pages. As it is, one has to click on one of the "+" menu items to expand the menu. When you are taken to the new page, you have to click the menu again to expand it if you wanted to go to another page within the same section. We'd like some way for the menu to expand automatically when a page is loaded or perhaps get a version of the javascript that would expand a particular item. Or maybe the answer is to pass something about the session on to the next page within a section. I am open to your suggestions but the result needs to be that once clicked, the menu continues to be expanded throughout that particular section of the site.
