How do i make the incomplete values submission page stay on my site?

Is there any way to make this a modal? as I have used source code

Unfortunately, I'm not entirely sure that I understand what it is that you are asking here?

Do you mean you want to save fields that are incomplete on your site? Or?

Can you please elaborate on this a bit more or provide us with an example workflow of what you meant by that?

Hello!

when a user clicks submit without filling in required fields, the "incomplete values page shows up, is there a way to make this message show up on a custom page or on the same page as the form instead of redirecting to the default page
