Drop Down Menu: Remove dropdown effect and transparency

[charltondurie]

I have the JavaScript file below that is used to run a drop down menu. How do I remove the drop down effect and the transparency effect from from it.

 

By drop down effect I mean instead of it just showing the whole menu instantly when you hover over the top button it just rolls it out down the page with a transparent effect.

 

var menu=function(){
var t=15,z=50,s=6,a;
function dd(n){this.n=n; this.h=[]; this.c=[]}
dd.prototype.init=function(p,c){
	a=c; var w=document.getElementById(p), s=w.getElementsByTagName('ul'), l=s.length, i=0;
	for(i;i<l;i++){
		var h=s[i].parentNode; this.h[i]=h; this.c[i]=s[i];
		h.onmouseover=new Function(this.n+'.st('+i+',true)');
		h.onmouseout=new Function(this.n+'.st('+i+')');
	}
}
dd.prototype.st=function(x,f){
	var c=this.c[x], h=this.h[x], p=h.getElementsByTagName('a')[0];
	clearInterval(c.t); c.style.overflow='hidden';
	if(f){
		p.className+=' '+a;
		if(!c.mh){c.style.display='block'; c.style.height=''; c.mh=c.offsetHeight; c.style.height=0}
		if(c.mh==c.offsetHeight){c.style.overflow='visible'}
		else{c.style.zIndex=z; z++; c.t=setInterval(function(){sl(c,1)},t)}
	}else{p.className=p.className.replace(a,''); c.t=setInterval(function(){sl(c,-1)},t)}
}
function sl(c,f){
	var h=c.offsetHeight;
	if((h<=0&&f!=1)||(h>=c.mh&&f==1)){
		if(f==1){c.style.filter=''; c.style.opacity=1; c.style.overflow='visible'}
		clearInterval(c.t); return
	}
	var d=(f==1)?Math.ceil((c.mh-h)/s):Math.ceil(h/s), o=h/c.mh;
	c.style.opacity=o; c.style.filter='alpha(opacity='+(o*100)+')';
	c.style.height=h+(d*f)+'px'
}
return{dd:dd}
}();

I think I have removed the transparency effect.

 

Note the 5th last line, is that correct? By changing

o; c.style.filter='alpha(opacity='+(o*100)+')'

to 1

 

var menu=function(){
var t=15,z=50,s=6,a;
function dd(n){this.n=n; this.h=[]; this.c=[]}
dd.prototype.init=function(p,c){
	a=c; var w=document.getElementById(p), s=w.getElementsByTagName('ul'), l=s.length, i=0;
	for(i;i<l;i++){
		var h=s[i].parentNode; this.h[i]=h; this.c[i]=s[i];
		h.onmouseover=new Function(this.n+'.st('+i+',true)');
		h.onmouseout=new Function(this.n+'.st('+i+')');
	}
}
dd.prototype.st=function(x,f){
	var c=this.c[x], h=this.h[x], p=h.getElementsByTagName('a')[0];
	clearInterval(c.t); c.style.overflow='hidden';
	if(f){
		p.className+=' '+a;
		if(!c.mh){c.style.display='block'; c.style.height=''; c.mh=c.offsetHeight; c.style.height=0}
		if(c.mh==c.offsetHeight){c.style.overflow='visible'}
		else{c.style.zIndex=z; z++; c.t=setInterval(function(){sl(c,1)},t)}
	}else{p.className=p.className.replace(a,''); c.t=setInterval(function(){sl(c,-1)},t)}
}
function sl(c,f){
	var h=c.offsetHeight;
	if((h<=0&&f!=1)||(h>=c.mh&&f==1)){
		if(f==1){c.style.filter=''; c.style.opacity=1; c.style.overflow='visible'}
		clearInterval(c.t); return
	}
	var d=(f==1)?Math.ceil((c.mh-h)/s):Math.ceil(h/s), o=h/c.mh;
	c.style.opacity=1;
	c.style.height=h+(d*f)+'px'
}
return{dd:dd}
}();
