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.
