Examples

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>

Notes

Remarks

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.
