First of all, there's no such tag as <nobr>  :-)

Second, an option element can only contain PCDATA, no other elements.

However, an option element *can* have a title attribute, so you can
just assign it a value, e.g.

{
     titleInfo =  //some dynamic values
     topArray[0] = new Option("Title Info", "");
     topArray[0].title = titleInfo;
}

HTH!
