{# Each field type is rendered by a template fragment, which is determined by the name of your form type class (DateTimePickerType -> date_time_picker) and the suffix "_widget". This can be controlled by overriding getBlockPrefix() in DateTimePickerType. See https://symfony.com/doc/current/form/create_custom_field_type.html#creating-the-form-type-template #} {% block date_time_picker_widget %}
