<option>

Inside <select> tag I can have some <option> items. Is there a way for me to specify that a specified <option> is not selectable, i.e. when user selects this <option> item, there is no reaction from screen. This is different from disabling the entire <select>.

Well, there's the <optgroup> element, but I don't think that's what you are after.

Some browsers support disabled on an option, by most do not. Best bet is to remove it.
