We use jQuery and Javascript to create this HTML code

<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
  <script src="//code.jquery.com/jquery-1.10.2.js"></script>
  <script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
  <link rel="stylesheet" href="/resources/demos/style.css">
  <script>
  $(function() {
    var availableTags = [
      "ActionScript",
      "AppleScript",
      "Asp",
      "BASIC",
      "C",
      "C++",
      "Clojure",
      "COBOL",
      "ColdFusion",
      "Erlang",
      "Fortran",
      "Groovy",
      "Haskell",
      "Java",
      "JavaScript",
      "Lisp",
      "Perl",
      "PHP",
      "Python",
      "Ruby",
      "Scala",
      "Scheme"
    ];
    $( "#tags" ).autocomplete({
      source: availableTags
    });
  });
  </script>

For the strings in the availableTags[] array, a parse.com cloud code loops through all the "suggestions" in the parse.com classes and stream them to the client's browser.

An real life example is available for your review at https://formgram.parseapp.com/formPage?formObjectId=KjuAOvq57n&formInstanceObjectId=Mb5iZfiWX6

The state field is an autocomplete field. Currently, only 4 states have been added to this autocomplete.

You can even add more states to this autocomplete if you'd like by simply typing in the name of another state at https://formgram.parseapp.com/formPage?formObjectId=twDYgj32wK

If you need additional help, let me know.
