<DragDropContext />

In order to use drag and drop, you need to have the part of your React tree that you want to be able to use drag and drop in wrapped in a <DragDropContext />. It is advised to just wrap your entire application in a <DragDropContext />. Having nested <DragDropContext />'s is not supported. You will be able to achieve your desired conditional dragging and dropping using the props of <Droppable /> and <Draggable />. You can think of <DragDropContext /> as having a similar purpose to the react-redux Provider component

Props

type Responders = {|
  // optional
  onBeforeDragStart?: OnBeforeDragStartResponder,
  onDragStart?: OnDragStartResponder,
  onDragUpdate?: OnDragUpdateResponder,
  // required
  onDragEnd: OnDragEndResponder,
|};

import type { Node } from 'react';

type Props = {|
  ...Responders,
  children: ?Node,
|};

See our type guide for more details

Basic usage

Using a class component

import React from 'react';
import { DragDropContext } from 'react-beautiful-dnd';

class App extends React.Component {
  onBeforeDragStart = () => {
    /*...*/
  };

  onDragStart = () => {
    /*...*/
  };
  onDragUpdate = () => {
    /*...*/
  };
  onDragEnd = () => {
    // the only one that is required
  };

  render() {
    return (
      <DragDropContext
        onBeforeDragStart={this.onBeforeDragStart}
        onDragStart={this.onDragStart}
        onDragUpdate={this.onDragUpdate}
        onDragEnd={this.onDragEnd}
      >
        <div>Hello world</div>
      </DragDropContext>
    );
  }
}

Using a function component

import React from 'react';
import { DragDropContext } from 'react-beautiful-dnd';

function App() {
  const onBeforeDragStart = useCallback(() => {
    /*...*/
  }, []);

  const onDragStart = useCallback(() => {
    /*...*/
  }, []);
  const onDragUpdate = useCallback(() => {
    /*...*/
  }, []);
  const onDragEnd = useCallback(() => {
    // the only one that is required
  }, []);

  return (
    <DragDropContext
      onBeforeDragStart={onBeforeDragStart}
      onDragStart={onDragStart}
      onDragUpdate={onDragUpdate}
      onDragEnd={onDragEnd}
    >
      <div>Hello world</div>
    </DragDropContext>
  );
}

Responders

Responders were previously known as Hooks

Responders are top level application events that you can use to perform your own state updates, style updates, as well as to make screen reader announcements.

Please see our Responders guide for detailed information about responders ❤️
