Generates a label tag for [[attribute]].
@param null|string|false $label the label to use. If `null`, the label will be generated via [[Model::getAttributeLabel()]].
If `false`, the generated field will not contain the label part.
Note that this will NOT be [[Html::encode()|encoded]].
@param null|array $options the tag options in terms of name-value pairs. It will be merged with [[labelOptions]].
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.
@return $this the field object itself.
Generates a label tag for [[ attribute ]] .
