“SuperFish” DropDown Menu

Superfish is an enhanced Suckerfish-style menu jQuery plugin that takes an existing pure CSS drop-down menu (so it degrades gracefully without JavaScript) and a lot of the much-sought-after enhancements. For details visit http://users.tpg.com.au/j_birch/plugins/superfish

JavaScript

We should include jQuery framework and superfish.js by pointing src attribute in the script tag to the .js files

<script type="text/javascript" src="jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="superfish.js"></script> 

The section of the index-#.html file contains these lines of code that initialize the script functionality with basic values:

<script type="text/javascript">
$(document).ready(function() {
   $('ul.sf-menu').superfish({
hoverClass: 'sfHover', // the class applied to hovered list items    
pathClass: 'overideThisToUse', // the class you have applied to list items that lead to the current page     
pathLevels: 1,  // the number of levels of submenus that remain open or are restored using pathClass     
delay: 800,  // the delay in milliseconds that the mouse can remain outside a submenu without it closing     
animation:  {opacity:'show'}, // an object equivalent to first parameter of jQuery’s .animate() method     
speed:  'normal', // speed of the animation. Equivalent to second parameter of jQuery’s .animate() method     
autoArrows: true, // if true, arrow mark-up generated automatically = cleaner source code at expense of initialisation performance     
dropShadows: true,  // completely disable drop shadows by setting this to false     
disableHI: false, // set to true to disable hoverIntent detection     
onInit: function(){}, // callback function fires once Superfish is initialised – 'this' is the containing ul     
onBeforeShow: function(){},  // callback function fires just before reveal animation begins – 'this' is the ul about to open     
onShow: function(){}, // callback function fires once reveal animation completed – 'this' is the opened ul     
onHide: function(){} // callback function fires after a sub-menu has closed – 'this' is the ul that just closed
   });
 });
</script> 

HTML

Below you can see general HTML script representation:

<ul class="sf-menu">

	<li> <a class="current" href="index.html">Home</a>

<ul>

	<li><a href="#">Free Mobile Website</a></li>


	<li><a href="#">Premium mobile templates</a></li>


	<li><a href="#">All devices templates</a></li>

</ul>
</li>


	<li><a href="#">templates</a></li>


	<li><a href="#">Demo</a></li>


	<li><a href="index-1.html">company</a></li>


	<li><a href="#">Contacts</a></li>

</ul>
