i am using jquery to sort my lists and i have run into a dead end. First, I checked the jquery site if theirs work on ie7, thats great, it does. next, i checked mine without the styles(so there possibly wont be anything that's intercepting or affecting jquery stuff). but i still get this weird error in ie7

when you sort items in the inner list(i have nested lists) they overlap each other, destroying the layout. if you sort the contianer lists, they work fine! here's a jsfiddle of what i mean:

note that if you drag demonstration one or two spots(in ie), it will overlap with the other links. BUT if you drag POC (it will select the whole thing including the links under it), it works fine!

is something wrong with my markup?
