A lightweight and pure CSS mega menu solution which allows you to add almost any components into your Bootstrap 4 navbar.

Bootstrap 3 framework is supported as well. You can download the Bootstrap 3 Version here.

How to use it:

1. Load the core stylesheet yamm.css into your Bootstrap project which has jQuery and bootstrap.min.js installed.

<link href="yamm/yamm.css" rel="stylesheet">

2. Create a mega menu from the regular Bootstrap navbar component. Possible CSS classes:

  • .yamm: required
  • .yamm-content: wrap content with padding
  • .yamm-fw: make dropdown menu full width
<nav class="yamm navbar navbar-expand-lg navbar-light bg-light fixed-top">
  <div class="container w-100"><a class="navbar-brand" href="#">Yamm Megamenu</a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbar-collapse-1" aria-controls="navbar-collapse-1" aria-expanded="false" aria-label="Toggle navigation"><span class="navbar-toggler-icon"></span></button>
    <div class="navbar-collapse collapse" id="navbar-collapse-1">
      <ul class="navbar-nav mr-auto">
        <!-- Classic list-->
        <li class="nav-item dropdown"><a class="nav-link dropdown-toggle" href="#" data-toggle="dropdown">List</a>
          <div class="dropdown-menu p-0">
            <!-- Content container to add padding-->
            <div class="yamm-content">

          </div>
        </li>
      </ul>
    </div>
  </div>
</nav>

3. Sometimes you need to revent unexpected menu close when using some components.

$(document).on('click', '.yamm .dropdown-menu', function(e) {
   e.stopPropagation()
})
