Code

protected function simplify(array &$form, FormStateInterface $form_state) {
  $field_name = $form_state
    ->get('field_name');
  $widget_element =& $form[$field_name]['widget'];

  // Hide the field label from displaying within the form, because JavaScript
  // displays the equivalent label that was provided within an HTML data
  // attribute of the field's display element outside of the form. Do this for
  // widgets without child elements (like Option widgets) as well as for ones
  // with per-delta elements. Skip single checkboxes, because their title is
  // key to their UI. Also skip widgets with multiple subelements, because in
  // that case, per-element labeling is informative.

    //   do, so generalize this.

  // Adjust textarea elements to fit their content.
