Star History

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
• 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:

• 📖 Rethinking drag and drop
• 🎧 React podcast: fast, accessible and beautiful drag and drop

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.
