Code

  // The rolereference_select widget doesn't need to create its own
  // element, it can wrap around the optionwidgets_select element.
  // This will create a new, nested instance of the field.
  // Add a validation step where the value can be unwrapped.
  $field_key = $element['#columns'][0];

    // to be passed down to the nested element.
    '#title' => $element['#title'],
    '#required' => $element['#required'],
