title: How to add please select option for the month year dropdown in Jquery Date Picker?
body: <p>I have a J query date picker like below(click the link to see the image). the datepicker is showing the month and year dropdowns in this date picker.</p>

  <p>by default the date picker is showing the current year and month selected. instead of that the year and month dropdowns needs to show a "Please Select" text. if user does not select month and year, then the popup should not get closed. popup should be closed only when options are selected. what options do we need to configure for this.</p>
  
  <pre><code>  $('#request-dob').datepicker({
      dateFormat: 'dd/mm/yy',
      changeMonth: true,
      changeYear: true,
      maxDate: new Date,
      yearRange: "-100:+0"
    });
  </code></pre>
