[](https://egghead.io/courses/beautiful-and-accessible-drag-and-drop-with-react-beautiful-dnd) ## Currently supported feature set ✅ - Vertical lists ↕ - Horizontal lists ↔ - Movement between lists (▤ ↔ ▤) - [Virtual list support 👾](/docs/patterns/virtual-lists.md) - unlocking 10,000 items @ 60fps - [Combining items](/docs/guides/combining.md) - Mouse 🐭, keyboard 🎹♿️ and touch 👉📱 (mobile, tablet and so on) support - [Multi drag support](/docs/patterns/multi-drag.md) - Incredible screen reader support ♿️ - we provide an amazing experience for english screen readers out of the box 📦. We also provide complete customisation control and internationalisation support for those who need it 💖 - [Conditional dragging](/docs/api/draggable.md#optional-props) and [conditional dropping](/docs/api/droppable.md#conditionally-dropping) - Multiple independent lists on the one page - Flexible item sizes - the draggable items can have different heights (vertical lists) or widths (horizontal lists) - [Add and remove items during a drag](/docs/guides/changes-while-dragging.md) - Compatible with semantic `<table>` reordering - [table pattern](/docs/patterns/tables.md) - [Auto scrolling](/docs/guides/auto-scrolling.md) - automatically scroll containers and the window as required during a drag (even with keyboard 🔥) - Custom drag handles - you can drag a whole item by just a part of it - Able to move the dragging item to another element while dragging (clone, portal) - [Reparenting your `<Draggable />`](/docs/guides/reparenting.md) - [Create scripted drag and drop experiences 🎮](/docs/sensors/sensor-api.md) - Allows extensions to support for [any input type you like 🕹](/docs/sensors/sensor-api.md) - 🌲 Tree support through the [`@atlaskit/tree`](https://atlaskit.atlassian.com/packages/confluence/tree) package - A `<Droppable />` list can be a scroll container (without a scrollable parent) or be the child of a scroll container (that also does not have a scrollable parent) - Independent nested lists - a list can be a child of another list, but you cannot drag items from the parent list into a child list - Server side rendering (SSR) compatible - see [resetServerContext()](/docs/api/reset-server-context.md) - Plays well with [nested interactive elements](/docs/api/draggable.md#interactive-child-elements-within-a-draggable-) by default ## Motivation 🤔 `react-beautiful-dnd` exists to create beautiful drag and drop for lists that anyone can use - even people who cannot see. For a good overview of the history and motivations of the project you can take a look at these external resources: - 📖 [Rethinking drag and drop](https://medium.com/@alexandereardon/rethinking-drag-and-drop-d9f5770b4e6b) - 🎧 [React podcast: fast, accessible and beautiful drag and drop](https://reactpodcast.simplecast.fm/17) ## Not for everyone ✌️ There are a lot of libraries out there that allow for drag and drop interactions within React. Most notable of these is the amazing [`react-dnd`](https://github.com/react-dnd/react-dnd). It does an incredible job at providing a great set of drag and drop primitives which work especially well with the [wildly inconsistent](https://www.quirksmode.org/blog/archives/2009/09/the_html5_drag.html) html5 drag and drop feature. `react-beautiful-dnd` is a higher level abstraction specifically built for lists (vertical, horizontal, movement between lists, nested lists and so on). Within that subset of functionality `react-beautiful-dnd` offers a powerful, natural and beautiful drag and drop experience. However, it does not provide the breadth of functionality offered by `react-dnd`. So `react-beautiful-dnd` might not be for you depending on what your use case is. ## Documentation 📖 ### About 👋 - [Installation](/docs/about/installation.md) - [Examples and samples](/docs/about/examples.md) - [Get started](https://egghead.io/courses/beautiful-and-accessible-drag-and-drop-with-react-beautiful-dnd) - [Design principles](/docs/about/design-principles.md) - [Animations](/docs/about/animations.md) - [Accessibility](/docs/about/accessibility.md) - [Browser support](/docs/about/browser-support.md) ### Sensors 🔉 > The ways in which somebody can start and control a drag - [Mouse dragging 🐭](/docs/sensors/mouse.md) - [Touch dragging 👉📱](/docs/sensors/touch.md) - [Keyboard dragging 🎹♿️](/docs/sensors/keyboard.md) - [Create your own sensor](/docs/sensors/sensor-api.md) (allows for any input type as well as scripted experiences) ### API 🏋️‍  - [`<DragDropContext />`](/docs/api/drag-drop-context.md) - _Wraps the part of your application you want to have drag and drop enabled for_ - [`<Droppable />`](/docs/api/droppable.md) - _An area that can be dropped into.
