(validate) how to add a unique error class name to a specific element

(validate) how to add a unique error class name to a specific element

Basically the problem im having is validating checkboxes.  The client does not want there to be a border around the checkboxes.  I would like to disable the the border somehow without affecting the other elements and I figure the simplest way to do this is to assign it a unique class with no styles.


Upon research I have found only how to change all the classes with something like this:

$(".selector").validate({
errorClass: "invalid"
})

How would I implement this on one specific element? Thanks.
