+ * Used for grouped form items. Can also be used as a theme wrapper for any

+ * See \Drupal\Core\Render\Element\RenderElement for more
+ * information on the #theme_wrappers render array property, and
+ * \Drupal\Core\Render\Element\container for usage of the container render
+ * element.
+ *
+ * Available variables:
+ * - attributes: HTML attributes for the containing element.
+ * - children: The rendered child elements of the container.
+ * - has_parent: A flag to indicate that the container has one or more parent
+     containers.
