- 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.
