I'm trying to format my list of items, where the html goes like this:

• Item 1
  • Item 1.1
  • Item 1.2
    • Item 1.2.1
    • Item 1.2.2
      • Item 1.2.2.1
      • Item 1.2.2.2
  • Item 1.3
• Item 2

And so on, hope you get the idea, that it can go deep infinet amout of times and now, I need to select and format UL of every LAST LI in any UL of the list. Do you have any idea? I've been stuck on this for 2 days now and all that I come up with has some "but", when it does't work. =/ Mike
