title: JQuery UI Datapicker : How to add next/previous year buttons
body: <p>I use the feature of selecting a year with a dropdown. I use it to set birthdays of people at least 18 years old. So far it works perfectly. I have set it up using theseg parameters:</p>
  
  <pre><code>        $('#datepicker').datepicker({
          changeMonth: true,
          changeYear: true,
                      dateFormat: 'dd-mm-yy',
                      minDate: '-100Y',
                      maxDate: '-18Y'
      });
  </code></pre>
  
  <p>However I'd like to have year navigation. Is it possible to add a next/previous year button?</p>
  
  <p>Thanks in advance for any help!</p>
