Highlighting the week selected in UI Datepicker

Highlighting the week selected in UI Datepicker

Hi guys,

A client is using Datapicker and wants to "
"In the monthly calendar can we have a red outline of the week selected."

Is there a nice way for me to do this?

My code is:

 <script type="text/javascript">
$(function() {
$("#datepicker").datepicker({altField: '#datepicker_alt', altFormat: 'yy-mm-dd',onSelect: function(date){$("#selectDay").submit();} });
$('#tabs').tabs();
});
</script>

Thanks in advance!
