How to delay the removal of a class for a dropdown

Question

I am trying to toggle a class on a navbar toggle but when you move your mouse the the dropdown menu it quickly removes the class and hides the menu. I think what it needs is a delay on just the removal of the class but the showing of the class can still be instant. Here is a screenshot of the hover issue https://i.imgur.com/o8ccCn9.gifv

Is there a manual way to write a toggle?

Codepen: https://codepen.io/JacobLett/pen/jaaQYG?editors=0110

This is the script so far

$(document).ready(function() {
 // executes when HTML-Document is loaded and DOM is ready

  // when you hover a toggle show its dropdown menu
  $(".navbar .dropdown-toggle").hover(function () {
     $(this).parent().toggleClass("show");
     $(this).parent().find(".dropdown-menu").toggleClass("show"); 
   });

    // hide the menu when the mouse leaves the dropdown
  $( ".navbar .dropdown-menu" ).mouseleave(function() {
    $(this).removeClass("show");  
  });

// document ready  
});

Update I guess .hover doesn't take into consideration the child elements. If it did my code would work. So I tried mouseenter and mouseleave but since the dropdown is position absolute it doesn't work with this either.

Answer 1

Ok, after trying a few javascript options I remembered the good old suckerfish menu which had you move the dropdown menu up a few pixels so the hover state would not break as you hovered over the gap between the anchor trigger and the menu itself.

So I kept my script the same but fired it only on desktop widths and then adjusted my CSS to remove the hover gap.

Answer 2

You could use the native JavaScript setTimeout() method...

$(document).ready(function() {
 // executes when HTML-Document is loaded and DOM is ready

  // when you hover a toggle show its dropdown menu
  $(".navbar .dropdown-toggle").hover(function () {
     $(this).parent().toggleClass("show");
     $(this).parent().find(".dropdown-menu").toggleClass("show"); 
   });

    // hide the menu when the mouse leaves the dropdown
  $( ".navbar .dropdown-menu" ).mouseleave(function() {
    setTimeout(function() {
      $(this).removeClass("show");
    }, 3000); // delay the removal of the 'show' class for 3 seconds
  });

// document ready  
});
