Flat Animated Dropdown Menu with jQuery and Animate.css

A modern flat designed dropdown menu which allows you to toggle sub menus with fancy CSS3 aniamtions based on Animate.css.

How to use it:

1. Include Font Awesome for dropdown icons (Optional).

<link href="//netdna.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet" type="text/css">

2. Include animate.css for CSS3 animations

<link href="//cdnjs.cloudflare.com/ajax/libs/animate.css/3.1.1/animate.min.css" rel="stylesheet">

3. The Html structure for the dropdown menu. Add the class 'animated' to the parent element, along with any of the animation names picked from animate.css. 

<nav class="animated flipInX">
  <ul>
    <li> <a href="#">
      <div class="fa fa-home"></div>
      </a> </li>
    <li> <a href="#"> About </a> </li>
    <li class="sub-menu"> <a href="#"> Products <i class="fa fa-angle-down"></i> </a>
      <ul>
        <li> <a href="#"> Product Item </a> </li>
        <li> <a href="#"> Product Item </a> </li>
        <li> <a href="#"> Product Item </a> </li>
      </ul>
    </li>
    <li class="sub-menu"> <a href="#"> Services <i class="fa fa-angle-down"></i> </a>
      <ul>
        <li> <a href="#"> Product Item </a> </li>
        <li> <a href="#"> Product Item </a> </li>
        <li> <a href="#"> Product Item </a> </li>
      </ul>
    </li>
    <li> <a href="#"> Contact Us </a> </li>
  </ul>
</nav>

4. The required CSS rules to style the dropdown menu.

nav ul {
  background: #2ecc71;
  list-style: none;
  margin: 0;
  padding: 0;
}

nav ul li {
  position: relative;
  display: inline-block;
  margin-right: -4px;
  text-align: center;
}

nav ul li:first-child a {
  background: #27ae60;
  width: 49px;
  padding: 15px 0;
}

nav ul li:last-child { margin: 0; }

nav ul li a {
  display: block;
  background: #2ecc71;
  padding: 15px 20px;
  color: #fff;
  font-size: 14px;
  text-decoration: none;
  transition: 0.2s linear;
}

nav ul li a:hover { background: #27ae60; }

nav ul li ul {
  position: absolute;
  top: 100%;
  left: 0;
  width: 240px;
  border-bottom: 4px solid #2ecc71;
}

nav ul li ul li {
  display: block;
  width: 100%;
  margin: 0;
  text-align: left;
}

nav ul li ul li a {
  display: block;
  background: #2c3e50;
  padding: 10px 15px;
}

  background: #2c3e50;
  width: auto;
  border-left: 4px solid transparent;
  padding: 10px 15px;
  font-size: 14px;
}

nav ul li ul li a:hover {
  background: #34495e;
  border-left: 4px solid #2ecc71;
}

5. Include jQuery library at the bottom of the document.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> 

6. A little JS to enable the dropdown menu.

$('.sub-menu ul').hide();
$(".sub-menu a").click(function () {
  $(this).parent(".sub-menu").children("ul").slideToggle("200");
  $(this).find("i.fa").toggleClass("fa-angle-up fa-angle-down");
});
