The HTML <optgroup> tag is used to group related <option> elements within a dropdown list. This is especially useful for long lists of options, making it easier for users to navigate. The <optgroup> tag has a single required attribute, label, which specifies a label or heading for the group of options.
<optgroup label="Group Name">
<option value="value1">Option 1</option>
<option value="value2">Option 2</option>
...
</optgroup>
