There's an overflow in the list. If anyone has an idea of what I'm doing wrong in this part of the code, I check this problem, but not a very good answer.
ListView doesn't work either, I'll try it with ItemControl, but it's not so easy to get the selected item
Maybe with Zindex? But doesn't work either
