Reply To: Jquery show hide in list not working fine

[Mottie]

Again, try hoverIntent (demo)

$(".parent.dropdown-submenu.mega-group").hoverIntent(
    function() {
       $(this).children('.dropdown-mega.level2').stop(true, false).show("500");
    },
    function(){
       $(this).children('.dropdown-mega.level2').stop(true, false).hide("500");
    }
);

I also included .stop(true, false) to stop previous animations.
