To display the data on the customer order view, on Thankyou page, My account order view and on email notifications, add this 2 code snippets in your function.php file:

$(this).removeClass("woocommerce-validated");

}

});
So, my question is, how can I remove the common field "CNP" from the second option "Persoana Juridica"?
