Taking your example....
-------About us (15)
-------------Members (12)
-------------History (22)
-------------Contact (14)
-------------Partners (24)
-------Products (16)
-------------Nintendo (17)
-------------Sony (23)
-------------Xbox (18)
-------------Gphone (25)
I have one horizontal menu that outputs the parents, in this case "About us" and "Products" and I have another menu in a horizontal line underneath this which shows only the children of that parent. So, for example, when on the Members page the submenu will only show Members, History, Contact and Partners, and when on, for example, Nintendo, the submenu will only show Nintendo, Sony, Xbox and Gphone.
I originally tried to make this work by using the "&innerTp" parameter but couldn’t get it to work. I am going to have another play around with it now, but any help is much appreciated.
I would love to attach a screenshot of my document tree but I am in the process of playing around with it before trnasfering my site over, and it just looks a mess with lots of pages named test1, test2 etc!
Thanks again Kongondo for your help

Fingers crossed it makes sense this time.
