Collapsible Menu (2)

I have a template that includes a menu area with 4 sample images. I would like javascript code that? makes this a Collapsible Menu when the plus sign is clicked. Attached is the template files that include a PDF file for the graphics and a [login to view URL] file that is to be used as the website template. A sample of a colapsible menu can be found at? <[login to view URL]>? . I would like for each plus sign to control the collapsible portion of the menu. If the plus sign is clicked then that menu expands and all other menu areas collapse. The expanded menu area shoud show a minus sign that is not clickable but the other non-expanded areas should show a plus sign that is clickable. The default vies is just like the sample [login to view URL] file where the first area is expanded by default. The titles should be hyperlinks that link to a html page that is relational to the menu title.
