Make hidden "state" field or not required on checkout

Hi,

How can I hide “stat” field on checkout page? Or make not required?

I tried this code, but doesnt work.

add_filter( 'woocommerce_billing_fields', 'woo_filter_state_billing', 10, 1 );
add_filter( 'woocommerce_shipping_fields', 'woo_filter_state_shipping', 10, 1 );

function woo_filter_state_billing( $address_fields ) {
	$address_fields['billing_state']['required'] = false;
	return $address_fields;
}

function woo_filter_state_shipping( $address_fields ) {
	$address_fields['shipping_state']['required'] = false;
	return $address_fields;
}

Kind Regards
Peter
