     * When this option is specified, the checkbox will be enclosed by a label tag. If you do not want any label, you
     * should explicitly set this option as `null`.
     * - `labelOptions`: array, the HTML attributes for the label tag. This is only used when the `label` option is
     * specified.
     *
     * The rest of the options will be rendered as the attributes of the resulting tag. The values will be HTML-encoded
     * using {@see \Yiisoft\Html\Html::encode()}. If a value is `null`, the corresponding attribute will not be
     * rendered.
