Eliminate the flickering effect on the dropdown menu

Is there a way to eliminate the annoying 'flicker' effect on my menu?

Whenever I click on 'Dropdown 1', I notice that Test 1 and Test 2 flicker. My assumption is that this is due to my use of the !important declaration.

Any suggestions or solutions?

  $(document).ready(function($) {
    $('.inline').find('.navtoggle').click(function(){

      //Expand or collapse this panel
      $(this).next().slideToggle('fast');

      //Hide the other panels
      $(".sub-menu").not($(this).next()).slideUp('fast');

    });
  });

Answer №1

It's important not to overdo the visibility settings in your CSS code. You can achieve the desired effect with a simpler approach like this:

$(this).next('ul').slideToggle();
$(this).closest('li').siblings().children('ul').slideUp();

Check out the Demo here

To reveal the sub-sub menu, you can make a minor adjustment to the CSS:

.primary-item > .sub-menu {
    display: none;
}

Answer №2

After troubleshooting the issue, I discovered that commenting out the slideUp command resolved the stuttering problem. This led me to investigate the selector responsible for this behavior:

console.log($(".sub-menu").not($(this).next()));

I found that the selector was targeting three different elements instead of just one. To rectify this and ensure only the correct element is selected, you can modify the selector as follows: add .navtoggle + before .sub-menu:

$(".navtoggle + .sub-menu").not($(this).next()).slideUp('fast')

Solution

Utilize jQuery for Enhanced Functionality

 $(document).ready(function($) {
    $('.inline').find('.navtoggle').click(function(){        

        //Expand or collapse this panel
        $(this).next().slideToggle('fast', function(){
          $(this).find(".sub-menu").slideDown('fast');
        });

       //Hide the other panels
       $(this).parent().siblings().find(".sub-menu").slideUp('fast');    

   });
});

Styling with CSS

.accordion-toggle {cursor: pointer;}
.sub-menu {display: none;}
