Description:

A horizontal dropdown navigation menu with a fancy 3D flipping animations when you open the sub-menus, based on CSS3 transitions and transforms. Built by waddington.

How to use it:

Create a multi-level navigation menu with nested Html lists following the Html structure like this:

<nav class="wrapper">
  <ul class="main">
    <li class="front"><a href="#">Item</a></li>
    <li class="front"><a href="#">Item</a></li>
    <li class="front"><a href="#">Hover</a>
      <ul class="sub">
        <li class="bottom"><a href="#">Sub Item</a></li>
        <li class="bottom"><a href="#">Sub Item</a></li>
        <li class="bottom"><a href="#">Sub Item</a></li>
      </ul>
    </li>
    <li class="front"><a href="#">Item</a></li>
    <li class="front"><a href="#">Item</a></li>
  </ul>
</nav>

The required CSS/CSS3 to style the navigation and animate the sub items with 3D flipping effects.
