Collaspible Menu component XML based

[L_RZA]

Hi everyone,
Im having some trouble with a xml menu that I have built, does anyone know there is a good resource for this sort of thing?
I am using the Collaspible Menu component, with xml. Now the problem is that the menu is working and looking good, but now my client is wanting for not only for it to have rollover states but for it to have varibles passed so that the currentPage is highlighted in the menu. This is possibly the stupidest request that I have ever had, as like I said before, they want it xml driven as it is going into a CMS and they want to be able to update it easily. As far as I know you cant do this, well I cant work it out, but if anyone knows or has seen a menu like this please let me know..
