you can use a function in the snap option:
new Draggable('my_draggable',{snap: function(x,y){
x = x<100 ? 100 : (x>500 ? 500 : x);
y = y<100 ? 100 : (y>500 ? 500 : y);
return [x,y];
});
This example snap function would limit the draggable within 100,100 and
500,500.
You can also call Position.within(element,x,y) inside the snap function to
test if the draggable is within the container.

Subject: [Rails-spinoffs] Restricting where a draggable can be dropped
Is there any way to restrict where a draggable can go? I have a section on
a web page that I would like to allow a draggable to only be moved within
it.
Do I need to look at Sortables, or is this even possible? I know I can
restrict to either vertical or horizontal movement, but I would like to
allow both - but only within a given area.
