How do I add or edit validation methods in this plugin? It’s already installed on my WordPress site, I just need to edit one of the fields. The How to Use documentation for this plugin just says, “You can add validation methods like url, date, dateiso, number, digits, creditcard, phoneUS etc from the class field of contact form 7.” Where are the class fields of in wordpress that I would be able to edit? Sorry for the basic question, I am very new to using jQuery in WordPress
