Auto Fill feature - save form and continue later

 Como faço para criar um formulário  que o usuário não envia apenas ele salva ou seja ele pode consultar o site novamente e alterar os dados que ele digitou anteriormente

Grato  

If I understood you correctly you want to save the form and continue later.

You can use Auto Fill feature, this method is saving the data automatically on user's computer using browser local storage.
