DatePicker Query

DatePicker Query


Hi All,
I am pretty new to jQuery UI and have recently started using
DatePicker plugin. Now I have a couple of queries related to
datepicker:
1. Is it possible to append a custom button/link like the Close,
Cancel, Clear etc links in the datepicker control thru settings. Also
I want to attach a custom function to that button. If not can I attach
a custom function when I click "Today"
2. Also I want to disable/close the datepicker when I click anywhere
outside the datepicker or the control which triggered the datepicker.
Please help. Thanks in advance.
