Adding fonctionnality to DatePicker

Adding fonctionnality to DatePicker


Hi everyone,
For our project we need to offer our users the ability to select a
date or
what we call a "fuzzy date", i.e. just a month/year or a year. As we
still
display a date picker, it would be nice to let the user click on the
month
or the year to use this "fuzzy date" format.
My problem is to add this behaviour without preventing a future
jQuery
update which could inactivate my dev.
Does anybody know a "how-to" add properly behaviours to ui widgets?
If none, it would be necessary for me to modify the standard widget,
if
so, I will add options for this and submit my modifications in this
place
... but it's not my preffered option...
thank's for any help you could offer,
Fred
