Build a Mega Menu with Ultimenu and Bootstrap in Drupal 8

Build a Mega Menu with Ultimenu and Bootstrap in Drupal 8

One of our customers asked how to build a mega menu in Drupal 8.

Mega menus are menus with multi-column navigation. They are fastly becoming a trend in web design.

The Ultimenu module allows you to insert Drupal blocks into a menu. You can easily use it to build fairly complex menu layouts.

In this tutorial, you will learn how to build a simple mega menu using the Ultimenu module and Bootstrap.

The customer was aiming at building a mega menu similar to the one on the image below:


The mega menu drop-downs should have 100% width. Their content must be Drupal blocks.

The Ultimenu Approach

The Ultimenu module generates a block for each menu you add in the menus page of your Drupal installation (admin/structure/menu).

You can place this block in the Block layout screen like any other block. The module turns menu items into dynamic regions in the block layout page.

That way you can insert blocks (custom blocks, views, etc) into these regions.

A block containing regions containing blocks:


Step #1. Install the Module

  • Install the module with composer:

composer require drupal/ultimenu

  • After downloading, click Extend and enable the module. No further dependencies are required:

Step #2. Create the menu

  • Click Structure > Menus.
  • Look for the Main Navigation
  • Click Edit menu.
  • Click the Add link button
  • Add the first level menu items:

The Travel link points to route:<nolink>. This parent element is only there to contain other elements:


Step #3. Configure the Ultimenu block

  • Click Structure > Ultimenu.
  • Tab select Main navigation in the vertical Ultimenu blocks
  • Click Save configuration:
  • Click Ultimenu regions.
  • Select Ultimenu:main: Travel

Ultimenu will create this region dynamically in the Block Layout page, so that you can place blocks in it.

  • Click Save Configuration:

The Ultimenu goodies tab has additional configuration options. I’m not going to check any of these options. Please, read the module’s documentation to understand how these options work, particularly if you’re building a multilingual site.

Step #4. The Image Block

In order to place an image in a block, you need to create a custom block type with the Image field.

  • Click Structure > Block layout > Custom block library > Block types.
  • Click the Add custom block type button:
  • Give the block type a proper name.
  • Click Save:
  • Click Manage fields.
  • Delete the Body field.
  • Click Add field.
  • Add the Image field.
  • Save it with the defaults.
  • Click Manage display.
  • Hide the Block label:
  • Click Structure > Block layout > Custom block library > Add custom block:
  • Click Block with Image:
  • Upload an image.
  • Click Save:

Step #5. The links block

There are many ways to obtain a block with links in four columns, for example with Views.

I’m working with a Bootstrap subtheme in this tutorial. I’m going to use a basic block with Bootstrap markup and classes.

Check out this tutorial in order to learn how to create a Bootstrap subtheme in Drupal.

  • Click Add custom block once again.
  • Select Basic block this time.
  • Give the block a proper name.
  • Select Full HTML as text format in the editor.
  • Click the Source button.
  • Paste following code in the editor window:
<div class="row">
<div class="col-sm-3">
<h3>Top destinations</h3>
<li><a href="#">North America</a></li>
<li><a href="#">Latin America</a></li>
<li><a href="#">Middle East</a></li>
<li><a href="#">Europe</a></li>
<li><a href="#">Africa</a></li>
<div class="col-sm-3">
<h3>Editor's choice</h3>
<li><a href="#">Best Hotel Deals</a></li>
<li><a href="#">Cruise Deals</a></li>
<li><a href="#">City Breaks</a></li>
<li><a href="#">Activities</a></li>
<li><a href="#">Culture</a></li>
<div class="col-sm-3">
<h3>City breaks</h3>
<li><a href="#">Paris</a></li>
<li><a href="#">Hong Kong</a></li>
<li><a href="#">Rome</a></li>
<li><a href="#">London</a></li>
<li><a href="#">Tokyo</a></li>
<div class="col-sm-3">
<h3>Custom menu</h3>
<li><a href="#">Disclaimer</a></li>
<li><a href="#">Privacy</a></li>
<li><a href="#">Advertisement</a></li>
<li><a href="#">Contact us</a></li> </ul>
  • Click Save.

Step #6. Place the Ultimenu block

  • Click Structure > Block layout.
  • Disable the default Main Navigation block.
  • Place the Ultimenu: Main navigation in the Navigation (collapsible) region.
  • Uncheck Display title.
  • Click Save block.

Step #7. Place the blocks in the “Travel” region

  • Scroll down to the bottom of the page.

You’ll see the dynamically generated region you assigned when configuring your Ultimenu.

  • Click Place block:
  • Place the image custom block in this region.
  • Uncheck Display title.
  • Click Save block.
  • Repeat the process with the Bootstrap markup block:
  • Rearrange the order of the blocks if needed.
  • Click Save blocks:

Now go to the front page of your site and take a look at the menu. A couple of CSS tweaks are required.

Step #8. The CSS

By default, the libraries file of your subtheme points to the style.css file inside the css/ folder within your Bootstrap subtheme.

  • Add the following code to that file:
/* Google fonts */
@import url(',700');
/* Menu Links */
.ultimenu__link {
text-transform: uppercase;
font-family: 'Roboto', sans-serif;
color: #000;
font-size: 1.1em;
display: inline-block;
font-weight: 700;
padding: 0.8em;
.has-ultimenu:hover {
background-color: #FFF;
/* Image Block */
#block-megamenuimage img {
width: 100%;
/* Links block */
#block-multicolumnblock {
width: 100%;
#block-multicolumnblock h3 {
text-transform: uppercase;
font-family: 'Roboto', sans-serif;
background: #000;
color: beige;
font-size: 1em;
display: inline-block;
font-weight: 700;
padding: 0.8em;
border-radius: 10px;
#block-multicolumnblock li {
list-style: none;
border-top: 0.5px dashed #333;
#block-multicolumnblock li:last-child {
border-bottom: 0.5px dashed #333;
#block-multicolumnblock li a {
text-decoration: none;
color: #333;
display: block;
line-height: 2.5em;

By now you should already have noticed how to tweak the menu by yourself:



You just learned how to build megamenus in Drupal using the Ultimenu module, Bootstrap and an easy to understand “Drupal block” approach.
