3) Describe problem:
I need buttons expand all colaspe all, as I understand, its necessary to have two additional functions.
This menu works great, but I need these "plugins"

The contractible headers script (http://www.dynamicdrive.com/dynamicindex1/navigate2.htm) is really just based on Switch Content script, which supports an "expand all" function. Take a look here: http://www.dynamicdrive.com/dynamicindex17/switchcontent.htm

Simply use Switch Content script (http://www.dynamicdrive.com/dynamicindex17/switchcontent.htm) instead on your page, setting everything up based on the instructions on that page. The code of Step 2 that you would have added to your page shows how to do an collapse all/ expand all link:


<div><a href="javascript:bobexample.sweepToggle('contract')">Contract All</a> | <a href="javascript:bobexample.sweepToggle('expand')">Expand All</a></div>
