Hide Billing and shipping information

Hi there,

Thanks for contact us! To hide billing and shipping section in order details page, plase copy and past this code at the end of functions.php file:

add_action( 'admin_enqueue_scripts', 'yith_wcmv_remove_information_from_order', 15 );

if ( ! function_exists( 'yith_wcmv_remove_information_from_order' ) ) {
	function yith_wcmv_remove_information_from_order() {
		if ( function_exists( 'yith_get_vendor' ) ) {
			global $pagenow;
			if ( ( 'post.php' == $pagenow && ! empty( $_GET['post'] ) && 'shop_order' == get_post_type( $_GET['post'] ) )
			     ||
			     ( 'post-new.php' == $pagenow && ! empty( $_GET['post_type'] ) && 'shop_order' == $_GET['post_type'] )
			) {
				$vendor = yith_get_vendor( 'current', 'user' );

				if ( $vendor->is_valid() && $vendor->has_limited_access() ) {
					$css = "#order_data .order_data_column:nth-child(2), #order_data .order_data_column:nth-child(3) {display: none;}";
					wp_add_inline_style( 'yith-wc-product-vendors-admin', $css );

					$js = 'jQuery("#order_data .order_data_column:nth-child(2)").add("#order_data .order_data_column:nth-child(3)").remove();';
					wc_enqueue_js( $js );
				}
			}
		}
	}
}

I hope this solution works fine for you.
