Help with slide-out menu

[Homer]

I have a slide out menu that I am hoping to use on my new site, at the moment it works very smoothly. view at www.barbadosvacations.co.uk (http://) As you can see I have menus 5,6,7,8, within menu1, what I am trying to do is include extra slide out menus 9, 10, 11 etc. in menus 2 & 3 etc. Can anyone give me an idea on how this is done? Any help aill be appreciated.

Regards

Homer
