I have a question related to Formit extra.
Is there a way to generate a custom css-class to input fields when error is found during the form validation? I would like to color those fields red wich are not valid.
So this kind of tag can be used in the css class attribute where "fieldname" is the field to validate against and "errorclass" is the custom css class [[+fi.error.<fieldname>:isnot=``:then=`<errorcssclass>`]]
When there is something wrong with the validation related to this field it shows the custom class...
