i try to make a clickable menu. it should be outputed as XML. i found a solution to make it possible to decend only the selected menues. but is there a easier solution? my goal is to first show only the first (level=0) level. if the user clicks on the menu it should select the second (level=1) level, but only from the menu he clicked. (so HAVING level<=1 doesn't help :( ) does anybody know a solution or a good reference for nested sets?

If you do not want to reinvent the wheel, you may want to try this implementation:
