{:navgoco}

Navgoco is a simple JQuery plugin which turns a nested unordered list of links into a beautiful vertical multi-level slide navigation, with ability to preserve expanded sub-menus between sessions by using cookies and optionally act as an accordion menu.

Getting Started

Download the plugin, unzip it and copy the files to your application directory and load them inside your HTML.

<head>
	<!-- Load JQuery -->
	<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
	<!-- Load jquery.cookie plugin (optional) -->
	<script type="text/javascript" src="/navgoco/src/jquery.cookie.js"></script>
	<!-- Load jquery.navgoco plugin js and css files -->
	<script type="text/javascript" src="/navgoco/src/jquery.navgoco.js"></script>
	<link rel="stylesheet" href="/navgoco/src/jquery.navgoco.css" type="text/css" media="screen" />
</head>

Sample menu html and activation code:

<script type="text/javascript">
	$(document).ready(function() {
		$('.nav').navgoco();
	});
</script>
<ul class="nav">
	<li><a href="#">1. Menu</a>
		<ul>
			<li><a href="#">1.1 Submenu</a></li>
			<li><a href="#">1.2 Submenu</a></li>
			<li><a href="#">1.3 Submenu</a></li>
		</ul>
	</li>
<!-- etc... -->
</ul>

You can also extend the default options:

<script type="text/javascript">
	$(document).ready(function() {
		$('.nav').navgoco({
			  caretHtml: '<i class="some-random-icon-class"></i>',
			  accordion: false,
			  openClass: 'open',
			  save: true,
			  cookie: {
				  name: 'navgoco',
				  expires: false,
				  path: '/'
			  },
			  slide: {
				  duration: 400,
				  easing: 'swing'
			  }
		  });
	});
</script>
