I have a module installed in my ZenCart so when people are checking out, they have the option to pay by check. As you can see from the photo, it's very large, and not very clean for when they checkout. (you can hardly see that you can also pay by PayPal.) I am looking for a way to make it so when they tick the circle as an option, the fields open up so they can then enter the information. IDK if this is Javascript or Ajax or can be done with PHP. Any help in the right direction is appreciated
