Multilevel Accordion Menu Plugin For jQuery

A nice, modern jQuery accordion plugin which gives you the ability to create a touch-enabled multilevel accordion menu with CSS3 powered expand / collapse animations.

How to use it:

1. Load the latest version of jQuery library and the core Javascript file in the document.

<script src="//code.jquery.com/jquery-2.1.4.min.js"></script>
<script src="js/script.js"></script>

2. Load the Font Awesome 4 for menu icons (OPTIONAL).

<link rel="stylesheet" href="font-awesome.min.css">

3. The markup structure for the accordion menu.

<nav>
  <div id="menu" class="menu">
    <div class="menu-header"> ACCORDION MENU </div>
    <ul>
      <li class="active"><a href="#"><i class="fa fa-home"></i>Home</a></li>
      <li><a href="#"><i class="fa fa-file-image-o"> </i>Gallery</a>
        <ul class="submenu">
          <li><a href="#"> Graphics</a></li>
          <li><a href="#"> Photoshop</a></li>
        </ul>
      </li>
      <li><a href="#"><i class="fa fa-cog"> </i>Services</a>
        <ul class="submenu">
          <li><a href="#"> Web Design </a>
            <ul class="submenu">
              <li><a href="#"> WordPress</a></li>
              <li><a href="#"> Joomla</a></li>
            </ul>
          </li>
          <li><a href="#"> Hosting</a></li>
          <li><a href="#"> Design </a></li>
        </ul>
      </li>
      <li><a href="#"><i class="fa fa-newspaper-o"> </i>News<span class="menu-label"> 8 </span></a></li>
      <li><a href="#"><i class="fa fa-user"> </i>About</a></li>
      <li><a href="#"><i class="fa fa-envelope"> </i> Contact</a></li>

  background: rgba(255, 255, 255, 0.3);
  border-radius: 100%;
  display: block;
  position: absolute;
  transform: scale(0);
}

.animate-ink {
  -moz-animation: ripple .3s linear;
  -ms-animation: ripple .3s linear;
  -o-animation: ripple .3s linear;
  -webkit-animation: ripple .3s linear;
  animation: ripple .3s linear;
}

@-moz-keyframes 'ripple' {
 100% {
 opacity: 0;
 transform: scale(2.5);
}
}

@-webkit-keyframes 'ripple' {
 100% {
 opacity: 0;
 transform: scale(2.5);
}
