I am posting in relation to the years drop down in the jQuery date picker, as I understand it will soon be going through a rewrite. I have gotten some grief from my users that it is non intuitive to pick the first date in the drop down to reload the years list with a prior range of years.
I have looked over the following post: http://forum.jquery.com/topic/jquery-datepicker-does-not-show-all-the-years
Frankly, I do not find that setting a large range to be a very good solution for every situation.
A more intuitive approach to this would provide the ability to include Earlier... and/or Later... selections (or similar keywords) to the top and bottom of the years drop-down, if applicable.
With this approach, I would set a large enough range of dates for the drop down to handle most users needs, and the others would see the Earlier... and Later... selections and it would be more to them that they could select years other than those that are shown in the list. Right now, it is just not obvious.
