While this works, it doesn't work the way you would expect. Typically, accordion menus start folded and open as clicked on. Also sub-menu items are usually folded until you go to their applicable header. This one works in exactly the opposite way on my site. I've tried other accordion menus on this site and didn't have this problem. Also, the end user experience of registering for downloading this was destroyed by what has to be the worst CAPTCHA implementation I have ever experienced; it took 6 attempts to get past it. All in all, it's hard for me to give this a higher rating. Maybe it works, but since there is no demo to be found on the site, I can't tell if it's the code or just me.
