The optgroup tag

The optgroup tag groups the items of a option drop-down list select.

Grouping is needed to give a common title to a certain group of list items. This title is specified in the label attribute of the optgroup tag.

html<select>
  <optgroup label="Country 1">
    <option>City 1</option>

  </optgroup>
  <optgroup label="Country 2">
    <option>City 3</option>
    <option>City 4</option>
  </optgroup>
</select>
