a quick question:

The appearance of the menu on mobile devices in magento 2 is :

enter image description here

with the 3rd level menu expanded by default.

Is there a way to make the 3rd level menu collapsed by default? something like this:

Okay, I came up with a solution. It may not be ideal, but it works for me. Hopefully somebody will find it useful.

It will depend on the base theme you're using, but first of all I had to comment out this line in styles-m.css:

.navigation .submenu:not(:first-child).expanded {
  // display: block !important;

In my own mobile stylesheet, that's set to the same breakpoint as where the responsive menu kicks in, I have this:

li.level0 ul {
li.level0 ul a {
.rm-expand {
  float:right;display:block;font-family: 'icons-blank-theme';font-size:42px;position:absolute;right: 7px;top: -6px;

Then finally, in my Javascript file I have:

require(['jquery', 'jquery/ui'], function($){
  // ... Irrelevant code omitted ...
  $(document).ready(function() {
    // ... Irrelevant code omitted ...
    $('li.level0 li.parent > a').append('<span class="rm-expand">&#58914;</span>');
    $('.rm-expand').click(function() {
    if ($(this).hasClass('open')) {
    } else {
    return false;
  // ... Irrelevant code omitted ...

You can add a custom jQuery widget to extend on the lib/web/mage/menu.js, how to do this is described here: https://devdocs.magento.com/guides/v2.3/javascript-dev-guide/javascript/js_practice.html

In your widget you can now override the '_toggleMobileMode' function from lib/web/mage/menu.js.

Search for this bit:

             * @param {jQuery.Event} event
            'click .ui-menu-item:has(a)': function (event) {
                var target;

                target = $(event.target).closest('.ui-menu-item');

                if (!target.hasClass('level-top') || !target.has('.ui-menu').length) {
                    window.location.href = target.find('> a').attr('href');

             * @param {jQuery.Event} event
            'click .ui-menu-item:has(.ui-state-active)': function (event) {
                this.collapseAll(event, true);

And remove or edit the check !target.hasClass('level-top'), this is where the 'click-through' functionality is only set on level-top links. The rest is styling.

  • This does the job, although i had to toggle the boolean in this.collapseAll(event, true);.
