Features:

• Lightweight: ~3 KB (~2 KB minified)
• Unobtrusive: Plays nice with JS turned off, uses its own namespace
• Cross-browser: Full A-Graded browsers support (Opera is supported through Ctrl + Left Click)
• Fully customizable: Menu styling can (and is intended to) be easily defined in external stylesheet
• Fast: Menu container is rendered on page load, and only changes position on click

How to use it

• Download Proto.Menu.js (or minified version) and include it in your page

<script type="text/javascript" src="js/prototype.js"></script>
<script type="text/javascript" src="js/Proto.Menu.js"></script>

• There's an optional CSS file if you do not wish to style menu yourself

<link rel="stylesheet" href="Proto.Menu.css" type="text/css" media="screen">

• Create array of links to display in a menu
  
  

var myLinks = [
	{name: 'Back', callback: function(){alert('back function called')}},
	{name: 'Forward', callback: function(){alert('Forward function called')}},
	{separator: true},
	{name: 'Reload', callback: function(){alert('Reload function called')}},
	{name: 'Disabled option', disabled: true},
	{name: 'Toggle previous option', callback: function(){
		var item = oLinks.find(function(l){return l.name == 'Disabled option'});
		item.disabled = item.disabled == false ? true : false;
	}}
]

• Initialize Proto.Menu class passing array of links

<script type="text/javascript">
new Proto.Menu({
	selector: '.contextmenu' // context menu will be shown when element with class name of "contextmenu" is clicked
	className: 'myContextMenu', // this is a class which will be attached to menu container (used for css styling)
	menuItems: myLinks // array of menu items
})
</script>
