When I hover over a menu, the menu li beneath is visible. It could be the div, but not sure. When I change to static and relative, they just shift down Here is my site http://ocart.site/opencart/

#menu > ul > li > div {
position: relative;
z-index: 5;

Answer 1

maybe you can more than z-index value

z-index: 9999

use try :

#menu > ul > li{
  position:relative;
  z-index: 9999
}
