jquery datepicker vertical scroll bar for month and year dropdown

jquery datepicker vertical scroll bar for month and year dropdown

Hi All,

I am using Jquery Datepicker which i have to show also in responsive design. When i verified the date calendar in mobile layout and expand the month dropdown. It does not have the scroll bar and showing a long month name dropdown like in below screen shot.



As you can see in above image month name is going in down and there is no scroll. Same issue is present for Year dropdown also..

Below is the piece of code used to initialize above calendar

  1.  $(document).ready(function () {
  2.                     $('#txtDob').datepicker({
  3.                         changeMonth: true,
  4.                         changeYear: true,
  5.                         yearRange: "-70:+0",
  6.                         dateFormat: "dd/mm/yy"
  7.                     });
  8.                 });

Please suggest here to provide some specific height so can provide the scroll bar.

Thanks,
Vikash
