Advanced XML Menu

I am using this fine XML-Driven Drop-down menu by senocular and I have tried to add the following: as soon as you click on something, the menu disappears and the only thing left are the active(chosen) items on each navigation level. In other words, if you choose food>vegetables>carrots, the menu disappears and you only see these three words standing on _y top position, next to each other:
food vegetables carrots. On mouse over the menu becomes visible again and these three have to be back in their original _y position in the menu.

Would you do this with the original menu items by hiding all the rest and moving these three up or would you hide the whole menu and use additional text fields to write the names of the active items?

Whatever the way, I’ve tried and just can’t do it. Any help will be most appreciated.
