Fancy Skewed Dropdown Menu With jQuery And CSS3 - UnusualMenu

UnusualMenu is a fancy, animated dropdown menu plugin for jQuery that uses CSS3 2D transforms for the pretty cool 'Skew' effect when the menu is opened on hover.

How to use it:

1. Create the dropdown menu from a nested nav list like this:

<nav>
  <ul>
    <li><a href="#"><span>Home</span></a></li>
    <li><a href="#"><span>Popular</span></a></li>
    <li> <a href="#"><span>Categories</span></a>
      <ul class="hidden">
        <li><a href="#"><span>Category 1</span></a></li>
        <li><a href="#"><span>Category 2</span></a></li>
        <li><a href="#"><span>Category 3</span></a></li>
        <li><a href="#"><span>Category 4</span></a></li>
      </ul>
    </li>
    <li><a href="#"><span>About</span></a></li>
    <li><a href="#"><span>Contact</span></a></li>
  </ul>
</nav>

2. The core CSS rules for the skewed dropdown menu:

nav {
  display: flex;
  justify-content: center;
}

ul { list-style: none; }

nav > ul > li {
  display: inline-block;
  float: left;
  box-sizing: border-box;
  width: 180px;
  margin-top: 50px;
}

a {
  text-decoration: none;
  background-color: #2d3f56;
  display: block;
  color: white;
  width: 180px;
  padding: 13px 0;
  text-align: center;
  font-family: Arial, Helvetica, sans-serif;
  font-size: 14px;
  box-sizing: border-box;
}

a:hover { background-color: #f93e3e; }

nav > ul > li > a { transform: skew(20deg); }

nav > ul > li > a > span {
  display: block;
  transform: skew(-20deg);
}

.hidden li:nth-child(odd) a {
  transform: skew(-25deg);
  background-image: linear-gradient(185deg, rgba(0,0,0,0.5), #2d3f56 30%)
}

.hidden li:nth-child(even) a {
  transform: skew(25deg);
  background-image: linear-gradient(175deg, rgba(0,0,0,0.5), #2d3f56 30%)
}

.hidden li:nth-child(even) span {
  display: block;
  transform: skew(-25deg);
}

.hidden li:nth-child(odd) span {
  display: block;
  transform: skew(25deg);
}

.hidden li:nth-child(even) a {
  position: relative;
  left: 5px;
  width: 200px;
}

.hidden li:nth-child(odd) a {
  position: relative;
  left: -5px;
  width: 200px;
}

.hidden { display: none; }

.hidden li > a { position: absolute; }

3. Load jQuery library and the jQuery UnusualMenu plugin at the end of the document. That's it.

<script src="//code.jquery.com/jquery-3.1.1.min.js"></script>
<script src="unusual menu.js"></script>
