I don't want to display shadow when dragging....
Please let me know if you have any doubts on this....
Thanks in Advance....

Answer 1

Listen for the dragStart event :
div.find("canvas").on('dragstart', function (event) {
so you can use DataTransfer.setDragImage() :
When a drag occurs, a translucent image is generated from the drag target (the element the dragstart event is fired at), and follows the mouse pointer during the drag. This image is created automatically, so you do not need to create it yourself. However, if a custom image is desired, the DataTransfer.setDragImage() method can be used to set the custom image to be used. The image will typically be an element but it can also be a or any other image element.
And update the container.onDragStart function to :
container.onDragStart = function (evt) {
container.selected(evt);
prevX = evt.clientX;
prevY = evt.clientY;
evt.originalEvent.dataTransfer.setDragImage(null, 0, 0); // add this line
};
Here's an example with a custom " shadow" iamge :
$(document).ready(function() {
// dont have a webserver so im using base64string instead
var maskedImageUrlb =
