problem with z-index on ie6

问题

Hy,

I run for several hours on a bug ie6, it was not the only one that I was locking it remains only to solve this one and I would finally be quiet.

I have a vertical menu that I built, the problem is that the second level menu does not overlap with that of the first level despite the z-index. Under FF is impeccable, in ie6 it fair.

here is my code, if you could help you relieve me greatly:

ie6 work on position relative more than absolute

    div#menu ul {
        position:relative;
        z-index:0;
    }
   div#menu ul ul{
        z-index:2;
    }
