title: jQuery UI Autocomplete autoFocus not working
body: <p>I am using jQuery UI autocomplete and trying to implement the autoFocus option.</p>
  
  <p>The documentation states the following:
  If set to true the first item will be automatically focused.</p>
  
  <p>I created a basic example and cannot get to work. I must be missing something obvious.  See here: <a href="http://jsfiddle.net/9bQJX/">http://jsfiddle.net/9bQJX/</a></p>
  
  <pre><code>$("#autocomplete").autocomplete({
      source: [
          "ActionScript",
          "AppleScript",
          "Asp",
          "BASIC",
          "C",
          "C++",
          "Clojure",
          "COBOL",
          "ColdFusion",
          "Erlang",
          "Fortran",
          "Groovy",
          "Haskell",
          "Java",
          "JavaScript",
          "Lisp",
          "Perl",
          "PHP",
          "Python",
          "Ruby",
          "Scala",
          "Scheme"
      ],
      autoFocus: true
  });
  </code></pre>
