How to add value to option list

How to add value from options to option list?

four five six ...

Options:
four 4
five 5
six 6

I try to modify dhtmlxcombo.js:
this.content.innerHTML=this.text+""+this.value+"";

but i need selected item without value…

The possible solution is to set an option label with a value initially:

four 4 five 5 six 6

And change a text in a combo header after an option is selected:

combo.attachEvent(“onSelectionChange”,function(){
var text = this.getComboText();
var arr = text.split(" ");
this.setComboText(arr[0]);
})

this work but problem with formating

in this construction it is not shown

<![CDATA[four4]]> <![CDATA[five5]]> <![CDATA[six6]]>

May be have a variant to separate the value text in other block?

works for me this variant:

four five six

this.content.innerHTML=this.text+" “+this.value+”";

combo.attachEvent(“onSelectionChange”,function(){
var text = this.getComboText();
var arr = text.split(" "); // two space, because space in text
this.setComboText(arr[0]);
})
