The HTML <option> tag also supports the following additional attributes −

<form action="/action_page.php">
<label for="class">Choose Grade:</label>
<select name="class" id="class">
<optgroup label="Grade 1">
<option value="A">A Section</option>
<option value="B">B Section</option>
<option value="C">C Section</option>
</optgroup>
<optgroup label="Grade 2">
<option value="A">A Section</option>
<option value="B">B Section</option>
<option value="C">C Section</option>
</optgroup>
</select>
<br>
