LightBoxes & Forms

Is it possible to have a 2-step form (essentially 2 forms) in 1 lightbox?
Ideally, we would like to have one button on the page that opens a lightbox with a first "form"with one field called Promo Code. After someone clicks submit and the promo code is accepted, we want another form to open up within the same lightbox.
Is this possible?


It would have to be one form setup like a multi-step form if you want to use the native Unbounce form. If you are custom coding your own form, you can set it up anyway you like (1 or 2 separate forms).

If you are using a native Unbounce form, it would have to be highly customised to your particular use case and based on my experience would need a lot of custom coding (JS/CSS).
