Jquery UI: draggable with constraints?

is it possible to set constraints for开发者_如何转开发 a draggable obeject? I have this line:

$("#info").draggable({ axis: 'y' });

i want this only to be draggable 200px towards the top. It should not be draggable towards the bottom? Is there any way to do that?

You can use a few of the shown options to achieve what you are looking for (like making a container div that is 200 px higher, etc).
