title: jQuery Datepicker - close on input click
body: <p>I am using <a href="http://jqueryui.com/demos/datepicker/" rel="noreferrer">jQuery Datepicker</a> and I have a little problem.</p>
  
  <p>If the datepicker is opened, and you click on the input field again, nothing happens.
  How can I change that.. the picker to be closed on input click if it is already opened ?</p>
  
  <p>Thanks in advance...</p>
