How to adapting blocktopmenu 1.5.1

[oslayer]

I tried adapt blocktopmenu in Presta 1.5.1

This module is based on superfishmenu.

 

And i have this trouble

in superfish-modified.js is a function

 

showSuperfishUl : function(){
  var o = sf.op,
   sh = sf.c.shadowClass+'-off',
   $ul = this.addClass(o.hoverClass)
 .find('>ul:hidden').css('visibility','visible');
  sf.IE7fix.call($ul);
  o.onBeforeShow.call($ul);

  $ul.animate(o.animation,o.speed,function(){ sf.IE7fix.call($ul); o.onShow.call($ul); });
  return this;
 }

 

I want add another similar function

showSuperfishUl : function(){
  var o = sf.op,
   sh = sf.c.shadowClass+'-off',
   $ul = this.addClass(o.hoverClass)
 .find('>div:hidden').css('visibility','visible');
  sf.IE7fix.call($ul);
  o.onBeforeShow.call($ul);

  $ul.animate(o.animation,o.speed,function(){ sf.IE7fix.call($ul); o.onShow.call($ul); });
  return this;
 }

But i don't know how do not understand the JS. Please help me...
