I am creating drop down menu using UL and I did. except I can't target four layer deep UL because as I assume target path code gets repeated and css gets confused.

I want to target last ul in this ul lu ul lu ul li ul sequence and tell him to opacity:0

ul is wrapped by #menu div. consequently I wrote: #menu li li li ul {opacity:0} I think css here can't tell the difference between li li ul and li li li ul so changes get applied to parent as well.

Any solutions that I am missing?

thanks in advance.

这就是我为我的多级下拉菜单所做的，仅使用 css .. 我希望这会对你有所帮助，你可以以同样的方式添加更多级别

    width:1000px;
    margin:0 auto;
