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. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

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.

Take a look at function test dragdrop6_test.html. I think it does what you''re asking for.

Hi, that''s ok if you need to limit only where draggable can go but i want to be able that draggable element jumps for 20px and can be dragged inside the parentNode is this possible too_? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

As for position constraints, you can also handle this with the same callback function, but you''ll need the Position object''s methods to determine the parent container''s coordinates and bound your movements within those. -- Christophe Porteneuve a.k.a.
