A modern, lightweight, performant, accessible and extensible drag & drop toolkit for React.

  • Built for React: exposes hooks such as useDraggable and useDroppable, and won't require you to re-architect your app or create additional wrapper DOM nodes.
  • Feature packed: customizable collision detection algorithms, multiple activators, draggable overlay, drag handles, auto-scrolling, constraints, and so much more.
  • Supports a wide range of use cases: vertical lists, horizontal lists, grids, multiple containers, nested contexts, variable sized list and grids, transformed items, virtualized lists.
  • Zero dependencies and modular: the core of the library weighs around 10kb minified and has no external dependencies. It's built around built-in React state management and context, which keeps the library lean.
  • Built-in support for multiple input methods: Pointer, mouse, touch and keyboard sensors.
  • Fully customizable & extensible: Customize every detail: animations, transitions, behaviours, styles. Build your own sensors, collision detection algorithms, customize key bindings and so much more.
  • Accessibility: Keyboard support, sensible default aria attributes, customizable screen reader instructions and live regions built-in.
  • Performance: It was built with performance in mind in order to support silky smooth animations.
  • Presets: Need to build a sortable interface? Check out @dnd-kit/sortable, which is a thin layer built on top of @dnd-kit/core. More presets coming in the future.


The core library of dnd kit exposes two main concepts:

Augment your existing components using the useDraggable and useDroppable hooks, or combine both to create components that can both be dragged and dropped over.

Handle events and customize the behaviour of your draggable elements and droppable areas using the <DndContext> provider. Configure sensors to handle different input methods.

Use the <DragOverlay> component to render a draggable overlay that is removed from the normal document flow and is positioned relative to the viewport.

Extensibility is at the core of dnd kit. It was built is built to be lean and extensible. It ships with the features we believe most people will want most of the time, and provides extension points to build the rest on top of @dnd-kit/core.

A prime example of the level of extensibility of dnd kit is the Sortable preset, which is built using the extension points that are exposed by @dnd-kit/core.

The primary extension points of dnd kit are:

  • Sensors
  • Modifiers
  • Constraints
  • Custom collision detection algorithms


Building accessible drag and drop interfaces is hard; dnd kit has a number of sensible defaults and starting points to help you make your drag and drop interface accessible:

  • Customizable screen reader instructions for how to interact with draggable items
  • Customizable live region updates to provide screen reader announcements in real-time of what is currently happening with draggable and droppable elements.
  • Sensible defaults for aria attributes that should be passed to draggable items

Check out our Accessibility guide to learn more about how you can help provide a better experience for screen readers.


Unlike most drag and drop libraries, dnd kit intentionally is not built on top of the HTML5 Drag and drop API. This was a deliberate architectural decision, that does come with tradeoffs that you should be aware of before deciding to use it, but for most applications, we believe the benefits outweigh the tradeoffs.

The HTML5 Drag and drop API has some severe limitations. It does not support touch devices, which means that the libraries that are built on top of it need to expose an entirely different implementation to support touch devices. This typically increases the complexity of the codebase and the overall bundle size of the library. Further, it requires workarounds to implement common use cases such as customizing the drag preview, locking dragging to a specific axis or to the bounds of a container, or animating the dragged item as it is picked up.

The main tradeoff with not using the HTML5 Drag and drop API is that you won't be able to drag from the desktop or between windows. If the drag and drop use-case you have in mind involves this kind of functionality, you'll definitely want to use a library that's built on top of the HTML 5 Drag and drop API. We highly recommend you check out react-dnd for a React library that's has a native HTML 5 Drag and drop backend.


Minimizing DOM mutations

dnd kit lets you build drag and drop interfaces without having to mutate the DOM every time an item needs to shift position.

This is possible because dnd kit lazily calculates and stores the initial positions and layout of your droppable containers when a drag operation is initiated. These positions are passed down to your components that use useDraggable and useDroppable so that you can compute the new positions of your items while a drag operation is underway, and move them to their new positions using performant CSS properties that do not trigger a repaint such as translate3d and scale. For an example of how this can be achieved, check out the implementation of the sorting strategies that are exposed by the @dnd-kit/sortable library.

This isn't to say that you can't shift the position of the items in the DOM while dragging, this is something that is supported and sometimes inevitable. In some cases, it won't be possible to know in advance what the new position and layout of the item until you move it in the DOM. Just know that these kind of mutations to the DOM while dragging are much more expensive and will cause a repaint, so if possible, prefer computing the new positions using translate3d and scale.

Synthetic events

dnd kit also uses SyntheticEvent listeners for the activator events of all sensors, which leads to improved performance over manually adding event listeners to each individual draggable node.

Working in the @dnd-kit repository

Running storybook

yarn start:storybook

Runs the storybook
Open http://localhost:6006 to view it in the browser.


Development workflow

You'll need to install all the dependencies in the root directory. Since the @dnd-kit is a monorepo that uses Lerna and Yarn Workspaces, npm CLI is not supported (only yarn).

yarn install

This will install all dependencies in each project, build them, and symlink them via Lerna

Development workflow

In one terminal, run tsdx watch in parallel:

yarn start

This builds each package to <packages>/<package>/dist and runs the project in watch mode so any edits you save inside <packages>/<package>/src cause a rebuild to <packages>/<package>/dist. The results will stream to to the terminal.

Working with the playground

You can play with local packages in the Parcel-powered playground.

yarn start:playground

This will start the playground on localhost:1234. If you have lerna running watch in parallel mode in one terminal, and then you run parcel, your playground will hot reload when you make changes to any imported module whose source is inside of packages/*/src/*. Note that to accomplish this, each package's start command passes TDSX the --noClean flag. This prevents Parcel from exploding between rebuilds because of File Not Found errors.

Important Safety Tip: When adding/altering packages in the playground, use alias object in package.json. This will tell Parcel to resolve them to the filesystem instead of trying to install the package from NPM. It also fixes duplicate React errors you may run into.

Running Cypress

(In a third terminal) you can run Cypress and it will run the integration tests against storybook.
