A small JQuery script that transforms a regular multi-level dropdown menu into a fixed navigation bar with a toggle icon on mobile devices. When you click on the toggle icon, an off-canvas menu slides out from the left hand side of your browser with a smooth CSS3 transition effect.
How to use it:
1. Create a regular multi-level dropdown navigation with a mobile menu toggle button.
<nav class="nav is-fixed" role="navigation">
<button class="nav-toggle">
<div class="icon-menu"> <span class="line line-1"></span> <span class="line line-2"></span> <span class="line line-3"></span> </div>
</button>
<div class="nav-container">
<ul class="nav-menu menu">
<li class="menu-item has-dropdown"> <a href="#!" class="menu-link">Home</a>
<ul class="nav-dropdown menu">
<li class="menu-item"> <a href="#!" class="menu-link">jQuery</a> </li>
<li class="menu-item has-dropdown"> <a href="#!" class="menu-link">Front-end</a>
<ul class="nav-dropdown menu">
<li class="menu-item"><a href="#!" class="menu-link">Html5</a></li>
<li class="menu-item"><a href="#!" class="menu-link">CSS3</a></li>
<li class="menu-item"><a href="#!" class="menu-link">Javascript</a></li>
</ul>
</li>
<li class="menu-item"> <a href="#!" class="menu-link">jQueryScript</a> </li>
</ul>
</li>
<li class="menu-item"> <a href="#!" class="menu-link">Blog</a> </li>
<li class="menu-item"> <a href="#!" class="menu-link">Contact</a> </li>
<li class="menu-item"> <a href="#!" class="menu-link">About</a> </li>
</ul>
</div>
</nav>
2. Add the following CSS/CSS3 snippets to style the navigation.

3. Include the latest version of jQuery JavaScript library at the end of the document.
<script src="//code.jquery.com/jquery-2.1.1.min.js"></script>
4. The jQuery script to active the responsive fixed navigation.
$(function() {
var html = $('html, body'),
navContainer = $('.nav-container'),
navToggle = $('.nav-toggle'),
navDropdownToggle = $('.has-dropdown');
// Nav toggle
navToggle.on('click', function(e) {
var $this = $(this);
e.preventDefault();
$this.toggleClass('is-active');
navContainer.toggleClass('is-visible');
html.toggleClass('nav-open');
});
// Nav dropdown toggle
navDropdownToggle.on('click', function() {
var $this = $(this);
$this.toggleClass('is-active').children('ul').toggleClass('is-visible');
});
// Prevent click events from firing on children of navDropdownToggle
navDropdownToggle.on('click', '*', function(e) {
e.stopPropagation();
});
});
