Positioning dropdown menu in IE and Firefox - html

Question

I'm trying to position this dropdown menu. It only works in Chrome, the submenu appear right below the hovered link. But in IE and firefox they all appear at the same place in the bottom left.

you need to update your css
in "#menu ul " remove the following properties
margin-top:12px;
float:left;
and add
top:56px;
left:0;
