title: jQuery UI Autocomplete - Arrows not toggling on the result list
body: <p>I have an autocomplete that's almost working as I want it to work. The problem that I have is that once I start searching for my items and I get a few suggestions, I would then like to use my arrows to click through the different suggestions. It toggles the different suggestions in the input field itself, but it doesnt move on to the list and "toggle" through them.</p>
  
  <p>This is my code</p>
  
  <pre><code>function () {
      $("#geosearch").autocomplete({
          minLength: 2,
          source: cities,
          focus: function (event, ui) {
              this.value = ui.item.label;
              event.preventDefault(); // Prevent the default focus behavior.
          },
          select: function( event, ui ) {
              addLocation(ui.item);
              return false;
          }
  
      });          
  }
  </code></pre>
  
  <p>What do I need to add to make it work? The funny thing is that all examples I find, have a working "arrow browsing" but my just wont do it :( </p>
