title: Autocomplete.js is not working with keyboard up and down arrow keys
body: <p>I am using the following jquery ui autocomplete function. This is working perfectly with mouse but by keyboard, I am not able to select any value. Have a look at the code.</p>
  
  <pre><code>$("#"+textBoxId).autocomplete("../common
     /autoSuggestValues.php?index="+index+"&amp;
    randValue="+Math.random(), {
      selectFirst: false,
      width:textBoxWidth,
      minChars: 2,
      autoFill: false,
      scroll: true,
      scrollHeight: 120,
      formatItem: function (rowdata) {
          var details = rowdata[0].split('@#@');
          return details[0];
      }
  });
  
  $('#'+textBoxId).result(function (event, data, formatted) { 
      var det   =  data[0].split("@#@");
      if(det[0] != 'No Match Found') {
          $('#'+textBoxId).val($.trim(det[0])).css('border','');  
          $('#'+hiddenId).val(det[1]);
          processAutoSuggOptFunc(optionalFunction); //process the optional  
       function using the another built function "processAutoSuggOptFunc"
      } else {
          $('#'+textBoxId).val('');   
          $('#'+hiddenId).val('');    
      }
  });
  </code></pre>
