Custom Signup Form.

Hi
I’m currently rebuilding the member signup system on my site and the new custom signup form is great as can now link extra info back into the wix-crm however it appears that currently this can only exist as a lightbox as when selecting your custom form there no option for a page where the form exists. I even tried copy the form and pasting to a normal page but still can find a way to tell the the system where to find the form. Is there anyway to have this form on a page rather than in a lightbox?
regards
