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.
    $num_children = count(Element::children($widget_element));
    if ($num_children == 0 && $widget_element['#type'] != 'checkbox') {
        $widget_element['#title_display'] = 'invisible';
    }
    if ($num_children == 1 && isset($widget_element[0]['value'])) {
        // @todo While most widgets name their primary element 'value', not all
        //   do, so generalize this.
        $widget_element[0]['value']['#title_display'] = 'invisible';
    }
    // Adjust textarea elements to fit their content.
    if (isset($widget_element[0]['value']['#type']) && $widget_element[0]['value']['#type'] == 'textarea') {
        $lines = count(explode("\n", $widget_element[0]['value']['#default_value']));
        $widget_element[0]['value']['#rows'] = $lines + 1;
