We have a multipage web application (a flow with lots of forms). The forms have lot of fields. Our client wants us to validate the fields on "Next" but allow the user to continue.
This introduces a few issues - unless we do a pop-up or keep the user on the same form, the validation messages will appear on the next form and won't be of much use to the user - since the flow is long and forms have lot of fields if we keep carrying the list of fields that failed validation along it becomes a really big/ugly message - more like a long paragraph.
I am looking for suggestions on how to handle both these issues - validate but continue - show validation messages without making it look like a paragraph
