Use of sup and sub in Combo

In the dropdown list you can use html code like for square meters for instance. But when you select it, it shows the html code instead. What to do?

console.log( myCombo.getInput().value ); returns something like
x + y2
because Text is Content Model for INPUT tag.

The dropdown list consists of DIV tags. So you can use other tags inside the dropdown list.

Maybe you need place DIV over Combo Input
and copy value from Input to div.innerHTML when combo OnChange
document.getElementById(‘fff443’).innerHTML = myCombo.getInput().value;

myCombo.attachEvent("onChange", function(code){
	document.getElementById('div_over_combo').innerHTML = myCombo.getInput().value;
	//console.log( myCombo.getInput().value );
