Generates a boolean input
This method is mainly called by [[activeCheckbox()]] and [[activeRadio()]].
@param string $type the input type. This can be either `radio` or `checkbox`.
@param Model $model the model object
@param string $attribute the attribute name or expression. See [[getAttributeName()]] for the format
about attribute expression.
@param array $options the tag options in terms of name-value pairs.
See [[booleanInput()]] for details about accepted attributes.
@return string the generated input element
