Multi Add-on Form

Hi Expert

I'm creating the add-on form.

And, I'd like to change the form that is displayed depending on the conditions in one preview button.

But, I think that it is possible to set only one form to one preview button.

If I set the multi form to one preview button, could you tell me how to do it?

Please give me some advice.

Wamr Regards,
