datepicker without days

datepicker without days

Hello everybody,

I'm trying to find a solution for configuring datepicker UI so that the user can choose only from months/years. Days are excluded, they do not appear.
I found a following solution:
$("#datepicker").datepicker({dateFormat: "mm/yy" });

but this doesn't solve the problem, as all days are visible. Can I make days in the UI invisible?

Thanks for all help.
