    You might be thinking of the <optgroup> element [1], which, as its name
suggests, is an element that contains groups of option elements. The
functionality that you describe is suggested in W3C documentation of the
<optgroup> element; however implementation is per browser make, model, and
platform, and I have never actually seen it implemented as you describe. IE
6 and Netscape 6 (in the PC world) implement it simply as an unselectable
header for the <option> elements that it contains.
