  • Today’s basic HTML question

    Can <optgroup> be nested within <optgroup>? Is the following example legal?

    <select>
       <optgroup label="A">
          <optgroup label="1">
                <option>Outlinepart1</option>
          </optgroup>
       </optgroup>
    </select>

    Answered! Optgroups may NOT be nested per HTML4 specification.
