This isYet another megamenu for Bootstrap 3 from Twitter. Lightweight and pure CSS megamenu that uses the standard navbar markup and the fluid grid system classes from Bootstrap 3. Work for fixed and responsive layout and has the facility to include (almost) any Bootstrap elements.
This project is currently hosted on Github and is the sequel to Bootstrap2 Yamm
Markup
Reuse navbar markup and add class .yamm at the top.
Then add your markup into the .dropdown-menu
Optionally use .yamm-content to wrap content with padding.
<nav class="navbar yamm navbar-default " role="navigation">
...
<ul class="nav navbar-nav">
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown</a>
<ul class="dropdown-menu">
<li>
<div class="yamm-content">
<div class="row">
...
</li>
</ul>
</li>
</ul>
...
</nav>
Grid Example
Width
By default every mega-dropdown will take the content size so is possible to use add .yamm-fw to .dropdown to expand it fullwidth
Yamm works better with fullwidth menus.
<nav class="navbar yamm navbar-default " role="navigation">
...
<ul class="nav navbar-nav">
<li class="dropdown yamm-fw">
...
</li>
</ul>
...
</nav>
More components
JavaScript
This code will prevent unexpected menu close when using some components (like accordion, forms, etc)
$(document).on('click', '.yamm .dropdown-menu', function(e) {
e.stopPropagation()
})
