I have a neat js wyswyg editor that works great. However I can only use existing controls.

I would like to add a drop-down style menu where I can define a unique css style for each option.

Any suggestions?

JS Code:
Code:
TINY={};

function T$(i){return document.getElementById(i)}
function T$$$(){return document.all?1:0}

TINY.editor=function(){
	var c=[], offset=-30;
	c['cut']=[1,'Cut','a','cut',1];
	c['copy']=[2,'Copy','a','copy',1];
	c['paste']=[3,'Paste','a','paste',1];
	c['bold']=[4,'Bold','a','bold'];
	c['italic']=[5,'Italic','a','italic'];
	c['underline']=[6,'Underline','a','underline'];
	c['strikethrough']=[7,'Strikethrough','a','strikethrough'];
	c['subscript']=[8,'Subscript','a','subscript'];
	c['superscript']=[9,'Superscript','a','superscript'];
	c['orderedlist']=[10,'Insert Ordered List','a','insertorderedlist'];
	c['unorderedlist']=[11,'Insert Unordered List','a','insertunorderedlist'];
	c['outdent']=[12,'Outdent','a','outdent'];
	c['indent']=[13,'Indent','a','indent'];
	c['leftalign']=[14,'Left Align','a','justifyleft'];
	c['centeralign']=[15,'Center Align','a','justifycenter'];
	c['rightalign']=[16,'Right Align','a','justifyright'];
	c['blockjustify']=[17,'Block Justify','a','justifyfull'];
	c['undo']=[18,'Undo','a','undo'];
	c['redo']=[19,'Redo','a','redo'];
	c['image']=[20,'Insert Image','i','insertimage','Enter Image URL:','http://'];
	c['hr']=[21,'Insert Horizontal Rule','a','inserthorizontalrule'];
	c['link']=[22,'Insert Hyperlink','i','createlink','Enter URL:','http://'];
	c['unlink']=[23,'Remove Hyperlink','a','unlink'];
	c['unformat']=[24,'Remove Formatting','a','removeformat'];
	c['print']=[25,'Print','a','print'];
