Mega menus are a powerful way to organize large navigation structures in a clean, user-friendly way. Whether you’re managing an eCommerce website, an agency site, or a multi-service business, a mega menu helps users quickly access categories, services, or content without digging through multiple dropdown levels.
If you’re using the Divi Theme, here’s the best part — you don’t need a plugin to build a mega menu. Divi gives you enough flexibility to design a fully custom, responsive mega menu using its layout builder, CSS, and a small script.
In this guide, you’ll learn step-by-step how to build a fully functional mega menu in Divi without installing any external plugin.
Why Create a Custom Mega Menu?
Mega menus are useful when your site has layered or complex navigation such as:
- Ecommerce stores with multiple product categories
- Digital agencies showcasing services, portfolios, and resources
- Learning platforms (LMS) with multiple courses
- Corporate websites with deep service architecture
Benefits:
- Improved user experience (UX)
- Higher navigation engagement
- Better structure for SEO and user flow
- No extra plugins → faster performance
What You’ll Need
Before starting, make sure you have:
- Divi Theme installed and activated
- Basic understanding of Divi Builder and CSS
Step 1: Create Your Main Menu & Assign Trigger Classes
Go to: Dashboard → Appearance → Menus
Create or update your main navigation menu and add a parent menu item that will open the mega menu (example: Services, Products, Solutions, etc.)
Example menu structure:
- Home
- About Us
- Mega Menu
- Contact Us
Now click the parent item (Mega Menu) and add this class:
mega-trigger menu-item-has-children
Note: If you don’t see the CSS class field, enable it from Screen Options → CSS Classes (top-right corner of the screen).
This tells Divi that this item will control the mega menu display.
Step 2: Create Your Global Header
Next, go to: Dashboard → Divi → Theme Builder
- Create a Global Header
- Open it in Divi Builder
- Add your logo, menu, and any design elements you’d like
This will act as your site’s main navigation area.
Step 3: Design Your Mega Menu Layout
Now create the mega menu area:
- Add a new Section below your main menu inside the same header layout.
- Give this section the following ID: mega-menu
Inside this section, design your mega menu content — for example:
Column 1: Icons + Title
Column 2: Menu Links
Column 3: Featured Posts + CTA Button
Useful modules:
- 💠 Blurb Module (icons + title)
- 🔗 Menu Module (show submenu)
- 🖼 Image or Icon module
- 🚀 Button module for CTA
Tip: Keep spacing consistent and avoid too many elements. Clean layout = better usability.
Step 4: Add CSS & JavaScript
Now we’ll enable hover functionality.
Add CSS:
Go to: Dashboard → Divi → Theme Options → Custom CSS
Paste this under Custom CSS
header {
z-index: 9;
position: relative;
}
#mega-menu {
position: absolute;
top: 100%;
left: 0;
width: 100%;
z-index: 9999;
opacity: 0;
transition: 0.3s all ease;
pointer-events: none;
}
#mega-menu.active {
opacity: 1;
pointer-events: all;
}
Add JavaScript
Now go to: Dashboard → Divi → Theme Options → Integration
Paste this under Add code to the <head> of your blog:
<script>
jQuery(document).ready(function($) {
$('.mega-trigger, #mega-menu').hover(function() {
$('#mega-menu').addClass('active');
},
function() {
$('#mega-menu').removeClass('active');
});
});
</script>
This script controls the hover behavior so the mega menu appears only when the user interacts with the designated menu item.
Step 5: Test Your Mega Menu
Now visit your website and hover over the trigger menu item (e.g., Mega Menu).
Test the following:
- Appears on hover
- Disappears when not hovered
- Looks good on desktop
