Usage

Load it after jQuery:

<script src="http://code.jquery.com/jquery-x.x.x.min.js"></script>

Set up your menu:

<nav id="main-nav">

    <li><a href="/">Home</a></li>

        <li><a href="/skills/computer-hacking">Computer Hacking</a></li>
        <li><a href="/skills/disco">Disco</a></li>
      </ul>
    </li>
    <li>
      <a href="/enemies">Enemies</a>
      <ul>
        <li><a href="/enemies/don">Don</a></li>
        <li><a href="/enemies/uncle-rico">Uncle Rico</a></li>
        <li>
          <a href="/enemies/rogue-ais">Rogue AIs ...</a>
          <ul>
            <li><a href="/enemies/rogue-ais/shodan">SHODAN</a></li>
            <li><a href="/enemies/rogue-ais/wintermute">Wintermute</a></li>
            <li><a href="/enemies/rogue-ais/neuromancer">Neuromancer</a></li>
            <li><a href="/enemies/rogue-ais/deus">Deus</a></li>
            <li><a href="/enemies/rogue-ais/megaera">Megaera</a></li>
          </ul>
        </li>
        <li><a href="/enemies/chickens">Chickens</a></li>
      </ul>
    </li>
    <li><a href="/art">Art</a></li>
    <li><a href="/contact">Contact</a></li>
  </ul>
</nav>

Throw in a bit of styling:

#main-nav ul { list-style: none; margin: 0; padding: 0; }
#main-nav ul li { display: inline-block; margin: 0 1em 0 1em; padding: 0.35em 0.75em 0.35em 0.75em; border-radius: 0.5em; }
#main-nav ul li.active { background: #999; }
#main-nav ul li.active a { color: #fff; text-decoration: none; }
.dropotron { background: #444; border-radius: 0.5em; list-style: none; margin: 0; min-width: 10em; padding: 0.75em 1em 0.75em 1em; }
.dropotron > li { border-top: solid 1px #555; margin: 0; padding: 0; }
.dropotron > li:first-child { border-top: 0; }
.dropotron > li > a { color: #ccc; display: block; padding: 0.5em 0 0.5em 0; text-decoration: none; }
.dropotron > li.active > a, .dropotron > li:hover > a { color: #fff; }
.dropotron.level-0 { margin-top: 1.25em; }
.dropotron.level-0:before { content: ''; position: absolute; border-bottom: solid 0.5em #444; border-left: solid 0.5em transparent; border-right: solid 0.5em transparent; top: -0.5em; }

And finally, call dropotron() on the menu's top level <ul>:

var foo = $('#main-nav > ul');
foo.dropotron();

That's about it.

Config

dropotron() can optionally override some or all of the following defaults:

foo.dropotron({
	selectorParent:		null,		// Parent jQuery object
	baseZIndex:			1000,		// Base Z-Index
	menuClass:			'dropotron',// Menu class (assigned to every <ul>)
	expandMode:			'hover',	// Expansion mode ("hover" or "click")
	hoverDelay:			150,		// Hover delay (in ms)
	hideDelay:			250,		// Hide delay (in ms; 0 disables)
	openerClass:		'opener',	// Opener class
	openerActiveClass:	'active',	// Active opener class
	submenuClassPrefix:	'level-',	// Submenu class prefix
	mode:				'fade',		// Menu mode ("instant", "fade", "slide", "zoom")
	speed:				'fast',		// Menu speed ("fast", "slow", or ms)
	easing:				'swing',	// Easing mode ("swing", "linear")
	alignment:			'left',		// Alignment ("left", "center", "right")
	offsetX:			0,			// Submenu offset X
	offsetY:			0,			// Submenu offset Y
	globalOffsetY:		0,			// Global offset Y
	IEOffsetX:			0,			// IE Offset X
	IEOffsetY:			0,			// IE Offset Y
	noOpenerFade:		true,		// If true and mode = "fade", prevents top-level opener fade.
	detach:				true,		// Detach second level menus (prevents parent style bleed).
	cloneOnDetach:		true		// If true and detach = true, leave original menu intact.
});
