title: react-final-form: how to submit per change in fields without button?
body: <p>I have a text field, dropdown, date picker, and etc. My form won't have a save button so I don't have any type of &quot;submit&quot;. For text field, I want the onSubmit to trigger to happen when the user enters enter button. For dropdown and date picker, it would call onSubmit when a user picks a different value aka onChange. It seems like you need a button or something of type submit to trigger onSubmit but it's not like I can put two types per Field. Any ideas on how I can trigger submit per field without any clicking any buttons?</p>
  <p>here is a sandbox where I tried to trigger onSubmit per field.
