public static RenderElement::processGroup(&$element, FormStateInterface $form_state, &$complete_form)
Arranges elements into groups.
This method is useful for non-input elements that can be used in and outside the context of a form.
Parameters
array $element: An associative array containing the properties and children of the element. Note that $element must be taken by reference here, so processed child elements are taken over into $form_state.
\Drupal\Core\Form\FormStateInterface $form_state: The current state of the form.
array $complete_form: The complete form structure.
Return value
array The processed element.
