Allows authors to group choices logically in a select element.
The following example shows how to use the OPTGROUP element to create groups of items in a drop-down list box.
<SELECT> <OPTGROUP LABEL="Alkaline Metals"> <OPTION>Lithium (Li)</OPTION> <OPTION>Sodium (Na)</OPTION> <OPTION>Potassium (K)</OPTION> </OPTGROUP> <OPTGROUP LABEL="Halogens"> <OPTION>Fluorine (F)</OPTION> <OPTION>Chlorine (Cl)</OPTION> <OPTION>Bromine (Br)</OPTION> </OPTGROUP> </SELECT>
In HTML 4.01, all OPTGROUP elements must be specified directly within a SELECT element. Groups may not be nested. You can add OPTGROUP elements only to a SELECT element located in the same window where the OPTGROUP elements are created. This element is available in HTML as of Microsoft Internet Explorer 6.
