Drag and drop

The basic sequence involved in drag and drop is:

• Move the pointer to the object
• Press, and hold down, the button on the mouse or other pointing device, to "grab" the object
• "Drag" the object to the desired location by moving the pointer to this one
• "Drop" the object by releasing the button

Dragging requires more physical effort than moving the same pointing device without holding down any buttons. Because of this, a user cannot move as quickly and precisely while dragging (see Fitts' law). However, drag-and-drop operations have the advantage of thoughtfully chunking together two operands (the object to drag, and the drop location) into a single action.{{cite conference |author=Buxton, W. |title=Chunking and Phrasing and the Design of Human-Computer Dialogues |book-title=Proceedings of the IFIP World Computer Congress |year=1986 |pages=475–480 |url=http://www.billbuxton.com/chunking.html |url-status=dead |archive-url=https://web.archive.org/web/20040607162853/http://www.billbuxton.com/chunking.html |archive-date=7 June 2004}}

Extended dragging and dropping (as in graphic design) can stress the mousing hand.

A design problem appears when the same button selects and drags items. Imprecise movement can cause an attempt to select an object to register as a dragging motion.

Another problem is that the target of the dropping can be hidden under other objects. The user would have to stop the dragging, make both the source and the target visible and start again. In classic Mac OS the top-of-screen menu bar served as a universal "drag cancel" target. This issue has been dealt with in Mac OS X with the introduction of Exposé.

Drag and drop, called click and drag at the time, was used in the original Macintosh to manipulate files (for example, copying them between disks{{cite web |url=http://www.folklore.org/StoryView.py?project=Macintosh&story=Disk_Swappers_Elbow.txt&topic=Technical&sortOrder=Sort%20by%20Date&detail=medium&showcomments=1 |title=Disk Swapper's Elbow |publisher=folklore.org}} or folders{{cite web |url=http://www.folklore.org/StoryView.py?project=Macintosh&story=The_Grand_Unified_Model_The_Finder.txt |title=The Grand Unified Model (2): The Finder |publisher=folklore.org}}). System 7 added the ability to open a document in an application by dropping the document icon onto the application's icon.

Apple added "Macintosh Drag and Drop" to System 7.5, extending "click and drag" to common clipboard operations like copying or moving textual content within a document. Content could also be dragged into the filesystem to create a "clipping file" which could then be stored and reused. Files could also be dropped on application windows, for example to enclose a document in an email, or add an image to a word processor document.

For most of its history Mac OS has used a single button mouse with the button covering a large portion of the top surface of the mouse. This may mitigate the ergonomic concerns of keeping the button pressed while dragging.

The Workplace Shell of OS/2 uses dragging and dropping extensively with the secondary mouse button, leaving the primary one for selection and clicking.

Its use like that of other advanced Common User Access features distinguished native OS/2 applications from platform-independent ports.

The HTML5 working draft specification includes support for drag and drop.{{cite web |url=http://www.w3.org/TR/2012/WD-html5-20120329/ |title=HTML5 W3C Working Draft |publisher=w3.org}} HTML5 supports different kinds of dragging and dropping features including:

• Drag and Drop texts and HTML codes
• Drag and Drop HTML elements
• Drag and Drop files

Based on needed action, one of the above types can be used. Note that when an HTML element is dragged for moving its current position, its ID is sent to the destination parent element; so it sends a text and can be considered as the first group.

Google's web-based e-mail application Gmail supports drag-and-drop of images and attachments in the latest Google Chrome browser and Apple's Safari (5.x). Google Images permits users to drag and drop image files into a browser to perform a reverse image search.

A drag and drop website builder (also called DIY website builders) offers a visual interface where users can create and customize their websites by simply “dragging” and “dropping” various elements onto a page without the need for development experience or knowledge of coding languages. No-code platforms have progressed well beyond the capabilities of early visual editors.{{cite web |last1=Groot |first1=Ralph de |title=Website Builder Statistics 2025 – 50 Mind Blowing Numbers |url=https://mycodelesswebsite.com/website-builder-statistics/ |website=My Codeless Website |access-date=20 May 2025 |language=en |date=3 November 2022}} With the advent of Artificial intelligence (AI), building a website has become even quicker.{{cite web |last1=Ryan |first1=Emma |title=I Tested 6 AI Website Builders: Which Should You Use? |url=https://www.websitebuilderexpert.com/website-builders/best-ai-website-builders/ |website=Website Builder Expert |publisher=Marketing VF Ltd |access-date=20 May 2025 |date=12 July 2023}}

Touch screen interfaces also include drag and drop, or more precisely, long press, and then drag, e.g. on the iPhone or Android home screens.

iOS 11 implements a drag-and-drop feature which allows the user to touch items (and tap with other fingers to drag more) within an app or between apps on iPads.{{Cite news|url=https://www.imore.com/ipad-drag-and-drop-multitasking-and-split-view-ios-11-everything-you-need-know|title=iPad Drag and Drop, Multitasking, and Split View in iOS 11: Everything you need to know!|work=iMore|access-date=2017-10-10}} On iPhones, the functionality is only available within the same app that the user started the drag.{{Cite web|url=https://www.theverge.com/2017/6/7/15752620/iphone-ios-11-drag-and-drop-apple-wwdc-2017|title=The iPhone is also getting drag and drop with iOS 11|last=Vincent|first=James|date=2017-06-07|website=The Verge|access-date=2017-06-23}}

Drag and drop is considered an important program construction approach in many end-user development systems. In contrast to more traditional, text-based programming languages, many end-user programming languages are based on visual components such as tiles or icons that are manipulated by end users through drag-and-drop interfaces.

Drag and drop is also featured in many shader editing programs for graphics tools, such as Blender.{{cite web|url=http://wiki.blender.org/index.php/Doc:2.6/Manual/Materials/Nodes|title=Render – Blender Reference Manual|work=blender.org|access-date=24 January 2014|archive-url=https://web.archive.org/web/20150323033003/http://wiki.blender.org/index.php/Doc:2.6/Manual/Materials/Nodes|archive-date=23 March 2015|url-status=dead}} Drag and drop also features in some video game engines, including Unreal Engine, GameMaker Studio, Construct 2 and, with expansion, Unity.

A common example is dragging an icon on a virtual desktop to a special trashcan icon to delete a file.

Further examples include:

• Dragging a data file onto a program icon or window for viewing or processing. For instance, dropping an icon that represents a text file into a Microsoft Word window signifies "Open this document as a new document in Word"
• Moving or copying files to a new location/directory/folder,
• Adding objects to a list of objects to be processed,
• Rearranging widgets in a graphical user interface to customize their layout,
• Dragging an attribute onto an object to which the command is to be applied,
• e.g. dragging a color onto a graphical object to change its color,
• Dragging a tool to a canvas location to apply the tool at that location,
• Creating a hyperlink from one location or word to another location or document.
• Most word processors allow dragging selected text from one point to another.
• Dragging a series of code blocks such as in Blender for designing shaders and materials.

• Mouse gesture
• Point and click
• Snap (computer graphics)
