Dynamic forms for cms item

How to create forms with Collections? I need 1 form per 1 item cms

Right now, thats not possible.

If fields are same for all forms, you can create one form with predefined fields and then inside of that form create field “CMS Item name” , and then have that input hidden and taking value from current CMS name.

And then in backend you will know for which cms item form was submited

Can you show how to do this?
