Archive widget dropdown alignment

Hi, I’m using typoXP 2.0, and it’s all fine except for the sidebar Archives widget drop-down isn’t indented properly. I know exactly why, it should be enclosed in a secondary pair of list tags which are absent. It’s driving me bananas, I can’t find where the little bit of code that makes it comes from so I can add them in. Any ideas please? – screenie

[I think that’s just the basic built in widget btw, it’s not one I’ve been and got from somewhere]
