My mega menu dropdown appears but you cannot click any of the items as the menu dissappears as soon as you move the mouse. This has been reported and fixed by yourselves once before. You applied this global custom css which solved it.
.item-design-mega-menu:hover:before, .menu-element .item-design-mega-menu:hover:before {
bottom: 0;
left: 0;
height: 70px;
}
I cannot understand what has changed.
