title: Show/Hide previous form field entries
body: <p>I was wondering if someone knows what controls the showing of previous form field entries in a form. </p>
  
  <p>So for example, if in the name field, I go to type 'John' it appears below the field. Is that a feature of the browser or is it javascript or something?</p>
  
  <p>Also, if it is the browser, is there a way I can turn this off for a given form?</p>
