[jQuery] SuperFish

[jQuery] SuperFish


Hello,
I have been using SuperFish Menu and on its online documentation it
shows various parameters:
$(document).ready(function(){
    $("ul.nav").superfish({
        hoverClass    : "sfHover",
        pathClass    : "overideThisToUse",
        delay        : 800,
        animation    : {opacity:"show"},
        speed        : "normal",
        oldJquery    : false, /* set to true if using jQuery version below 1.2
*/
        disableHI    : false, /* set to true to disable hoverIntent detection
*/
        onInit        : function(){},
        onBeforeShow    : function(){},
        onShow        : function(){},
        onHide        : function(){}
    });
});
What is pathClass?
Animation is a jQuery function?
And what values can speed take?
There is no description on the web site.
I am creating an ASP.NET control for this and I need to know.
Thanks,
Miguel
