Hello. I have a very large form. When some field is missing or bad, the "submit" button does nothing and the required fields are shown in red. What I need to do is that when some fields has an erros, the form scrolls to the beginning, all the messages appear at the beginning of the form along with a message like "PLease correct the following error before send your form", or, that a popup appears indicated what I have mentioned. What's the best way to do that?
Thanks in advance.
