public function InlineEntityFormBase::form in Inline Entity Form 8

Creates a form element for a field.

If the entity associated with the form is new (i.e., $entity->isNew() is TRUE), the 'default value', if any, is pre-populated. Also allows other modules to alter the form element by implementing their own hooks.

Parameters

\Drupal\Core\Field\FieldItemListInterface $items: An array of the field values. When creating a new entity this may be NULL or an empty array to use default values.

array $form: An array representing the form that the editing element will be attached to.

\Drupal\Core\Form\FormStateInterface $form_state: The current state of the form.

int $get_delta: Used to get only a specific delta value of a multiple value field.

Return value

array The form element array created for this field.
