I'm having an issue with form/field validation with the forms submission.
Required text fields that are missed are outlined red to indicate their need for input, which is fine, but the submit button stays active (blue) during this time.
I've also noticed that in my form that 'attachments' which are marked as required but missed, there is no indication for their input after the fact, ie, no red outline. The submit button also stays a blue-active.
This has been confusing for a number of my testers.
My suggestion would be to 'gray out' the submit button until all requirements are met and to add a visual indicator (red outline) for 'attachments' if missed.
