class Widget

Provides a widget element.

A form wrapper containing basic properties for the widget, attach the widget elements to this wrapper. This element renders to an empty string.

@property $field_parents The 'parents' space for the field in the form. Most widgets can simply overlook this property. This identifies the location where the field values are placed within $form_state->getValues(), and is used to access processing information for the field through the WidgetBase::getWidgetState() and WidgetBase::setWidgetState() methods. @property $delta The order of this item in the array of sub-elements. (0, 1, 2, etc.)
