## โ ๏ธ Maintenance & support
This library continues to be relied upon heavily by Atlassian products, but we are focused on other priorities right now and have no current plans for further feature development or improvements.
It will continue to be here on GitHub and we will still make critical updates (e.g. security fixes, if any) as required, but will not be actively monitoring or replying to issues and pull requests.
We recommend that you donโt raise issues or pull requests, as they will not be reviewed or actioned until further notice.

## Core characteristics
- Beautiful and [natural movement](/docs/about/animations.md) of items ๐
- [Accessible](/docs/about/accessibility.md): powerful keyboard and screen reader support โฟ๏ธ
- [Extremely performant](/docs/support/media.md) ๐
- Clean and powerful api which is simple to get started with
- Plays extremely well with standard browser interactions
- [Unopinionated styling](/docs/guides/preset-styles.md)
- No creation of additional wrapper dom nodes - flexbox and focus management friendly!
## Get started ๐ฉโ๐ซ
We have created [a free course on `egghead.io` ๐ฅ](https://egghead.io/courses/beautiful-and-accessible-drag-and-drop-with-react-beautiful-dnd) to help you get started with `react-beautiful-dnd` as quickly as possible.
[](https://egghead.io/courses/beautiful-and-accessible-drag-and-drop-with-react-beautiful-dnd)
## Currently supported feature set โ
- Vertical lists โ
- Horizontal lists โ
- Movement between lists (โค โ โค)
- [Virtual list support ๐พ](/docs/patterns/virtual-lists.md) - unlocking 10,000 items @ 60fps
- [Combining items](/docs/guides/combining.md)
- Mouse ๐ญ, keyboard ๐นโฟ๏ธ and touch ๐๐ฑ (mobile, tablet and so on) support
- [Multi drag support](/docs/patterns/multi-drag.md)
- Incredible screen reader support โฟ๏ธ - we provide an amazing experience for english screen readers out of the box ๐ฆ. We also provide complete customisation control and internationalisation support for those who need it ๐
- [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 ๐ฅ)
- 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 ๐ฎ](/docs/sensors/sensor-api.md)
- Allows extensions to support for [any input type you like ๐น](/docs/sensors/sensor-api.md)
- ๐ฒ 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 ๐ค
`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:
- ๐ [Rethinking drag and drop](https://medium.com/@alexandereardon/rethinking-drag-and-drop-d9f5770b4e6b)
- ๐ง [React podcast: fast, accessible and beautiful drag and drop](https://reactpodcast.simplecast.fm/17)
## Not for everyone โ๏ธ
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.
