delay drop down menu

Hi Sakin,

I finally got around to properly search for a solution.
No plugin found unfortunately.
I have found a js script, but I don’t know where to implement it and I think there’s names in there that might not be correct (for the theme).
Could you help me tweak it so it will work on our website?

var timer;

$(".parent").on("mouseover", function() {
  clearTimeout(timer);
  openSubmenu();
}).on("mouseleave", function() {
  timer = setTimeout(
    closeSubmenu
  , 1000);
});

function openSubmenu() {
  $(".submenu").addClass("open");
}
function closeSubmenu() {
  $(".submenu").removeClass("open");
}
