jQuery datepicker years shown

With the jQuery datepicker, how does one change the year range that is displayed? On the jQuery UI site it says the default is "10 years before and after the current year are shown". I want to use this for a birthday selection and 10 years before today is no good. Can this be done with the jQuery datepicker or will I have to use a different solution?

If you look down the demo page a bit, you'll see a "Restricting Datepicker" section. Use the dropdown to specify the "Year dropdown shows last 20 years" demo , and hit view source:

$("#restricting").datepicker({ 
    yearRange: "-20:+0", // this is the option you're looking for
    showOn: "both", 
    buttonImage: "templates/images/calendar.gif", 
    buttonImageOnly: true 
});

You'll want to do the same (obviously changing -20 to -100 or something).

Why not show the year or month selection boxes?

$( ".datefield" ).datepicker({
    changeMonth: true,
    changeYear: true,
    yearRange:'-90:+0'
});
