`<optgroup>` HTML option group element

The <optgroup> HTML element creates a grouping of options within a <select> element.

In customizable <select> elements, the <legend> element is allowed as a child of <optgroup>, to provide a label that is easy to target and style. This replaces any text set in the <optgroup> element’s label attribute, and it has the same semantics.

  <optgroup label="Theropods">
    <option>Tyrannosaurus</option>

    <option>Deinonychus</option>
  </optgroup>
  <optgroup label="Sauropods">
    <option>Diplodocus</option>
    <option>Saltasaurus</option>
    <option>Apatosaurus</option>
  </optgroup>
</select>

  display: block;
  margin-bottom: 10px;
}

Attributes

This element includes the global attributes.
