form with filter

Hi everyone,

I am trying to create a form with multi steps options.

• Page 1 : select your region
• Page 2 : Select your zip code
• Page 3 : I’d like to keep those info on the top of the page.

I dont want to create a page (N°3) for each zip code its gonna take me ages to do it. 🙂

Do you have any idea?
Thank you
