/**
* Generates a tag that contains the first validation error of [[attribute]].
* Note that even if there is no validation error, this method will still return an empty error tag.
* @param array|boolean $options the tag options in terms of name-value pairs. It will be merged with [[errorOptions]].
* The options will be rendered as the attributes of the resulting tag. The values will be HTML-encoded
* using [[Html::encode()]]. If a value is null, the corresponding attribute will not be rendered.
*
* The following options are specially handled:
*
* - tag: this specifies the tag name. If not set, "div" will be used.
*
* If this parameter is false, no error tag will be rendered.
*
* If you set a custom `id` for the error element, you may need to adjust the [[$selectors]] accordingly.
*
* @return $this the field object itself
