const [visible, setVisible] = useState(false)

const [renderInline, setRenderInline] = useInputValue(false, 'checked')

const [closeOnClick, setCloseOnClick] = useInputValue(false, 'checked')

const [closeOnOutsideClick, setCloseOnOutsideClick] = useInputValue(false, 'checked')

const clickClose = event => {
