[Xymon] changing new xymon menu to allow for horizontal drop downs

I'd like to add some horizontal drop down menus to the new xymon menu, similar to what is shown here:

http://sperling.com/examples/menuh/

With the old menu, it was pretty simple, I just added some code like this:

['Analysis', null, null, ['Web Servers', null, null, ['Averages', null, null, [CPU Utilization, '/hobbit-cgi/......

Of course that doesn't work with the new menu, so I have to start over. Can anyone point me to some example code that does what I'm trying to do? I'm not a web programmer by any means, so any help is greatly appreciated.

Thanks, Tom
