Select option groupings (select-optgroup)

Related <option> elements in a <select> must be grouped with a labeled <optgroup>; do not simulate grouping with disabled/empty options, punctuation, or other visual separators.


Missing or empty optgroup label:

Groups are provided with <optgroup>, but one group has an empty label and another lacks the label attribute entirely.


Note: Possible to automatically test. Tools can detect <optgroup> elements with a missing or empty label attribute.
