Best JavaScript drag-and-drop plugin?
simonw: I've had lots of success with the draggable/droppable modules from jQuery UI. They cover a lot of tricky cases (don't start dragging unless the mouse has moved more than a few pixels, revert to original position if the drag fails, arrange draggables in to "groups" so they only interact with the correct droppables) and generally do everything I need straight out of the box.The only problem I've had with them has been advanced code that needs to make independent modifications to the position of the draggable during the drag, but a post on their support forum solved that one for me: http://forum.jquery.com/topic/trying-to-manipulate-the-posit...In the past I've used YUI 2's drag and drop to good effect, but jQuery UI's is much easier to get started with.
