title: jquery autocomplete trigger dropdown on input:focus
body: <p>I'm using the popular JQuery Autocomplete plugin below.</p>
  
  <p><a href="http://jqueryui.com/demos/autocomplete/" rel="noreferrer">http://jqueryui.com/demos/autocomplete/</a></p>
  
  <p>Currently if you type a phrase the drop down appears but when you click away it hides. This is fine. However the only way to bring the dropdown back is to either click in the input field and type further characters or press keydown.</p>
  
  <p>Any ideas on how to trigger the dropdown of results when the user clicks in the input field? I've tried to trigger the focus event for the input field but that doesn't work. I somehow need to manually call the autocomplete dropdown event when the input field is focused. Thanks.</p>
