Drag the W3Schools image into the rectangle.
Drag and drop is a very common feature. It is when you "grab" an object and drag it to a different location.

Note: Drag and drop does not work in Safari 5.1.2.
The example below is a simple drag and drop example:
It might seem complicated, but lets go through all the different parts of a drag and drop event.
First of all: To make an element draggable, set the draggable attribute to true:
Then, specify what should happen when the element is dragged.

This is done by calling the event.preventDefault() method for the ondragover event:
When the dragged data is dropped, a drop event occurs.
In the example above, the ondrop attribute calls a function, drop(event):
