Creating a user-friendly mobile menu that collapses to save space while keeping parent links active is essential for improving navigation and user experience on smaller screens.
In this article, we will guide you through the process of designing a collapsible mobile menu in Divi that maintains the functionality of parent links.
Add the CSS Code to the Custom CSS area
Go to WordPress Dashboard → Divi → Theme Options → General Tab → Custom CSS
Add the following CSS code:
/* Proper Collapsable Mobile Menu */
/* Style the icon's placeholder */
ul.et_mobile_menu li.menu-item-has-children .mobile-toggle,
ul.et_mobile_menu li.page_item_has_children .mobile-toggle,
.et-db #et-boc .et-l ul.et_mobile_menu li.menu-item-has-children .mobile-toggle,
.et-db #et-boc .et-l ul.et_mobile_menu li.page_item_has_children .mobile-toggle {
width: 44px;
height: 100%;
padding: 0px !important;
max-height: 44px;
position: absolute;
right: 0px;
top: 0px;
z-index: 999;
background-color: transparent;
border-bottom: 0;
text-align: center;
}
ul.et_mobile_menu > li.menu-item-has-children,
ul.et_mobile_menu > li.page_item_has_children,
ul.et_mobile_menu > li.menu-item-has-children .sub-menu li.menu-item-has-children,
.et-db #et-boc .et-l ul.et_mobile_menu > li.menu-item-has-children,
.et-db #et-boc .et-l ul.et_mobile_menu > li.page_item_has_children,
.et-db #et-boc .et-l ul.et_mobile_menu > li.menu-item-has-children .sub-menu li.menu-item-has-children {
position: relative;
}
.et_mobile_menu .menu-item-has-children > a,
.et-db #et-boc .et-l .et_mobile_menu .menu-item-has-children > a {
background-color: transparent;
}
/* Hide the Sub-menu */
ul.et_mobile_menu .menu-item-has-children .sub-menu,
#main-header ul.et_mobile_menu .menu-item-has-children .sub-menu,
.et-db #et-boc .et-l ul.et_mobile_menu .menu-item-has-children .sub-menu,
.et-db #main-header ul.et_mobile_menu .menu-item-has-children .sub-menu {
display: none !important;
visibility: hidden !important;
}
/* Show the sub-menu when the + icon is clicked */
ul.et_mobile_menu .menu-item-has-children .sub-menu.visible,
#main-header ul.et_mobile_menu .menu-item-has-children .sub-menu.visible,
.et-db #et-boc .et-l ul.et_mobile_menu .menu-item-has-children .sub-menu.visible,
.et-db #main-header ul.et_mobile_menu .menu-item-has-children .sub-menu.visible {
display: block !important;
visibility: visible !important;
}
/* Create the opening/closing icon using the SVG Icons */
ul.et_mobile_menu li.menu-item-has-children .mobile-toggle .dt-icons,
.et-db #et-boc .et-l ul.et_mobile_menu li.menu-item-has-children .mobile-toggle .dt-icons {
top: 10px;
position: relative;
}
/* Hide the closing icon if the sub-menu is not open */
ul.et_mobile_menu li.menu-item-has-children:not(.dt-open) .mobile-toggle .dt-close-icon,
.et-db #et-boc .et-l ul.et_mobile_menu li.menu-item-has-children:not(.dt-open) .mobile-toggle .dt-close-icon {
display: none;
}
/* Hide the opening icon if the sub-menu is open */
ul.et_mobile_menu li.menu-item-has-children.dt-open > .mobile-toggle .dt-open-icon,
.et-db #et-boc .et-l ul.et_mobile_menu li.menu-item-has-children.dt-open > .mobile-toggle .dt-open-icon {
display: none;
}
Add the JavaScript Code to the Integration tab
Go to WordPress Dashboard → Divi → Theme Option → Integration tab → Header
Add the following JS code:
<script id="dt-collapsable-menu-items">
jQuery(function ($) {
$(document).ready(function () {
$('body ul.et_mobile_menu li.menu-item-has-children, body ul.et_mobile_menu li.page_item_has_children').append(
'<span class="mobile-toggle no-smooth-scroll" aria-label="toggle sub menu"><svg class="dt-icons dt-open-icon" xmlns="http://www.w3.org/2000/svg" height="1em" viewBox="0 0 448 512"><path d="M256 80c0-17.7-14.3-32-32-32s-32 14.3-32 32V224H48c-17.7 0-32 14.3-32 32s14.3 32 32 32H192V432c0 17.7 14.3 32 32 32s32-14.3 32-32V288H400c17.7 0 32-14.3 32-32s-14.3-32-32-32H256V80z"/></svg><svg class="dt-icons dt-close-icon" xmlns="http://www.w3.org/2000/svg" height="1em" viewBox="0 0 384 512"><path d="M342.6 150.6c12.5-12.5 12.5-32.8 0-45.3s-32.8-12.5-45.3 0L192 210.7 86.6 105.4c-12.5-12.5-32.8-12.5-45.3 0s-12.5 32.8 0 45.3L146.7 256 41.4 361.4c-12.5 12.5-12.5 32.8 0 45.3s32.8 12.5 45.3 0L192 301.3 297.4 406.6c12.5 12.5 32.8 12.5 45.3 0s12.5-32.8 0-45.3L237.3 256 342.6 150.6z"/></svg></span>',
);
$('ul.et_mobile_menu li.menu-item-has-children .mobile-toggle, ul.et_mobile_menu li.page_item_has_children .mobile-toggle').click(function (event) {
event.preventDefault();
event.stopPropagation();
$(this).parent('li').toggleClass('dt-open');
$(this)
.parent('li')
.find('ul.children')
.first()
.toggleClass('visible');
$(this)
.parent('li')
.find('ul.sub-menu')
.first()
.toggleClass('visible');
});
$('.mobile-toggle')
.on('mouseover', function () {
$(this).parent().addClass('is-hover');
})
.on('mouseout', function () {
$(this).parent().removeClass('is-hover');
});
});
});
</script>
The result will be something similar to what's displayed on the below screenshot:
