Плагин выпадающего меню «SuperFish»

Superfish является расширенным JQuery плагином в стиле Suckerfish, в качестве основы плагина было взято выпадающее меню на CSS и HTML (это меню продолжит работать даже если у пользователя будет отключен javaScript), добавлено много востребованных усовершенствований.

JavaScript

Необходимо подключить файл jQuery и superfish.js, указав src атрибут в тег .js файлов

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

Файл index-#.html содержит следующие строки кода, которые инициализируют скрипт с основными значениями:

<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>
