Building a Simple Mega Menu

GeneratePress doesn’t have a mega menu by default, simply because not everyone would use it and it adds a decent amount of CSS.

However, creating a simple mega menu in GeneratePress isn’t very hard. You only need to add some CSS and then structure your menu correctly.

First, add the CSS:

@media (min-width: 769px) {
    nav .main-nav .mega-menu {
        position: static;

    nav .main-nav .mega-menu > ul {
        position: absolute;
        width: 100%;
        left: 0 !important;
        display: flex;
        flex-wrap: wrap;

    nav .main-nav .mega-menu > ul > li > a {
        font-weight: bold;

    nav .main-nav .mega-menu>ul>li {
        display: inline-block;
        width: 25%;
        vertical-align: top;

    nav .main-nav .mega-menu.mega-menu-col-2>ul>li {
        width: 50%;

    nav .main-nav .mega-menu.mega-menu-col-3>ul>li {
        width: 33.3333%;

    nav .main-nav .mega-menu.mega-menu-col-5>ul>li {
        width: 20%;

    nav .main-nav .mega-menu > ul > li:hover > a,
    nav .main-nav .mega-menu > ul > li:focus > a,
    nav .main-nav .mega-menu > ul > li[class*="current-"] > a,
    nav .main-nav .mega-menu ul ul {
        background-color: transparent !important;
        color: inherit;

    nav .main-nav .mega-menu ul .sub-menu {
        position: static;
        display: block;
        opacity: 1;
        visibility: visible;
        width: 100%;
        box-shadow: 0 0 0;
        left: 0;
        height: auto;

    nav .main-nav .mega-menu ul.toggled-on .sub-menu {
        pointer-events: auto;

    nav .main-nav .mega-menu .sub-menu .menu-item-has-children .dropdown-menu-toggle {
        display: none;

Over time, it’s important to check back here to make sure the CSS hasn’t been updated or improved.

Then we just need to structure the menu correctly.

Go into Appearance > Menus and create your new menu or use your existing menu.

You’re basically going to have your main parent item – the item that displays in your main navigation bar.

Then you’ll have a series of child items below this main parent item – those are your mega menu headings.

Then, your grandchild item under the child items are displayed as your links under each heading.

Here’s an example:

Now that our structure is built, open the main parent item, and give it the mega-menu class.

If you don’t see the CSS Classes input field as shown below, see this article.

Now when we save, this is our result:

Live Mega Menu

By default, we have 4 columns.

We can adjust this by adding another class to our parent item.

These are the available column classes:


So if we want two columns, our class would look like this:
