Get started 👩‍🏫

Alex Reardon has created a free course on egghead.io 🥚 (using react-beautiful-dnd) to help you get started with @hello-pangea/dnd as quickly as possible.

Currently supported feature set ✅

Vertical lists ↕
Horizontal lists ↔
Movement between lists (▤ ↔ ▤)
Virtual list support 👾 - unlocking 10,000 items @ 60fps
Combining items
Mouse 🐭, keyboard 🎹♿️ and touch 👉📱 (mobile, tablet and so on) support
Multi drag support
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 and conditional 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
Compatible with semantic <table> reordering - table pattern
Auto scrolling - 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 />
Create scripted drag and drop experiences 🎮
Allows extensions to support for any input type you like 🕹
🌲 Tree support through the @atlaskit/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()
Plays well with nested interactive elements by default

Motivation 🤔

@hello-pangea/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:

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. It does an incredible job at providing a great set of drag and drop primitives which work especially well with the wildly inconsistent html5 drag and drop feature. @hello-pangea/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 @hello-pangea/dnd offers a powerful, natural and beautiful drag and drop experience. However, it does not provide the breadth of functionality offered by react-dnd. One shortcoming is that grid layouts are not supported (yet). So @hello-pangea/dnd might not be for you depending on what your use case is.

API 🏋️‍

<DragDropContext /> - Wraps the part of your application you want to have drag and drop enabled for
<Droppable /> - An area that can be dropped into. Contains <Draggable />s
<Draggable /> - What can be dragged around
resetServerContext() - Utility for server side rendering (SSR)
