The main steps to drag and drop are to define a drop zone (i.e. A target element for the file drop) and to define event handlers for the drop and dragover events. These steps are described below, including example code snippets. The full source code is available in MDN's drag-and-drop repository (pull requests and/or issues are welcome).

Drag and Drop (DnD) is powerful User Interface concept which makes it easy to copy, reorder and deletion of items with the help of mouse clicks. This allows the user to click and hold the mouse button down over an element, drag it to another location, and release the mouse button to drop the element there.
To achieve drag and drop functionality with traditional HTML4, developers would either have to either have to use complex JavaScript programming or other JavaScript frameworks like jQuery etc.
Now HTML 5 came up with a Drag and Drop (DnD) API that brings native DnD support to the browser making it much easier to code up.

HTML 5 DnD is supported by all the major browsers like Chrome, Firefox 3.5 and Safari 4 etc.
Drag and Drop Events
There are number of events which are fired during various stages of the drag and drop operation. These events are listed below −
| Sr.No. | Events & Description |
|---|---|
| 1 | dragstart Fires when the user starts dragging of the object. |
| 2 | dragenter Fired when the mouse is first moved over the target element while a drag is occurring. A listener for this event should indicate whether a drop is allowed over this location. If there are no listeners, or the listeners perform no operations, then a drop is not allowed by default. |
| 3 | dragover This event is fired as the mouse is moved over an element when a drag is occurring. Much of the time, the operation that occurs during a listener will be the same as the dragenter event. |
| 4 | dragleave This event is fired when the mouse leaves an element while a drag is occurring. Listeners should remove any highlighting or insertion markers used for drop feedback. |
| 5 | drag Fires every time the mouse is moved while the object is being dragged. |
| 6 | drop The drop event is fired on the element where the drop was occurred at the end of the drag operation. A listener would be responsible for retrieving the data being dragged and inserting it at the drop location. |
| 7 | dragend Fires when the user releases the mouse button while dragging an object. |

Note − Note that only drag events are fired; mouse events such as mousemove are not fired during a drag operation.
The DataTransfer Object
The event listener methods for all the drag and drop events accept Event object which has a readonly attribute called dataTransfer.
The event.dataTransfer returns DataTransfer object associated with the event as follows −
The DataTransfer object holds data about the drag and drop operation. This data can be retrieved and set in terms of various attributes associated with DataTransfer object as explained below −
| Sr.No. | DataTransfer attributes and their description |
|---|---|
| 1 | dataTransfer.dropEffect [ = value ]
|
| 2 | dataTransfer.effectAllowed [ = value ]
|
| 3 | dataTransfer.types Returns a DOMStringList listing the formats that were set in the dragstart event. In addition, if any files are being dragged, then one of the types will be the string 'Files'. |
| 4 | dataTransfer.clearData ( [ format ] ) Removes the data of the specified formats. Removes all data if the argument is omitted. |
| 5 | dataTransfer.setData(format, data) Adds the specified data. |
| 6 | data = dataTransfer.getData(format) Returns the specified data. If there is no such data, returns the empty string. |
| 7 | dataTransfer.files Returns a FileList of the files being dragged, if any. |
| 8 | dataTransfer.setDragImage(element, x, y) Uses the given element to update the drag feedback, replacing any previously specified feedback. |
| 9 | dataTransfer.addElement(element) Adds the given element to the list of elements used to render the drag feedback. |

Step 2 - Dropping the Object
To accept a drop, the drop target has to listen to at least three events.
The dragenter event, which is used to determine whether or not the drop target is to accept the drop. If the drop is to be accepted, then this event has to be canceled.
The dragover event, which is used to determine what feedback is to be shown to the user. If the event is canceled, then the feedback (typically the cursor) is updated based on the dropEffect attribute's value.
Finally, the drop event, which allows the actual drop to be performed.
Following is the example to drop an object into another object −
This will produce the following result −
