19+ Bootstrap 5 Mega Menu Responsive/Drop Down Examples

Yet another Bootstrap 5 responsive mega menu with multilevel dropdown examples and search box. This mega navigation system is built with the Bootstrap 5 navbar component with multiple levels of dropdowns. Besides this, a mega dropdown is also placed inside the main navbar that contains the Bootstrap grid layout for links, cards, and link groups.

You are not limited to place only cards and links inside the mega dropdown, you can also place any Bootstrap element like forms, accordions, and images, etc. The menu comes with an animated hamburger button (for mobile view) to toggle nav items.

Basically, this mega menu doesn’t require any JavaScript function as it uses Bootstrap 5 native dropdowns and navbar components. Even, the additional styles are not necessary, the menu is quite compatible with Bootstrap 5.0.2 and above.  Anyhow, a little JS function requires to toggle the hamburger on small screens.

3. Load the Bootstrap 5 JS by adding the following CDN link just before closing the body tag.

<!-- Bootstrap 5 JS -->
<script src='https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js'></script>

4. Finally, initialize the hamburger button in the JS function to make the mega menu responsive.

document.addEventListener('click',function(e){
  // Hamburger menu
  if(e.target.classList.contains('hamburger-toggle')){
    e.target.children[0].classList.toggle('active');
  }
})
