Drag-and-drop sortable component for nested data and hierarchies

React Sortable Tree

A React component for Drag-and-drop sortable representation of hierarchical data. Checkout the demo for a demonstration of some basic features. Checkout the storybook for advanced usage.

Getting started

Install react-sortable-tree using npm.

# NPM
npm install react-sortable-tree --save

# YARN
yarn add react-sortable-tree

ES6 and CommonJS builds are available with each distribution.
For example:

// This only needs to be done once; probably during your application's bootstrapping process.
import 'react-sortable-tree/style.css';

// You can import the default tree with dnd context
import SortableTree from 'react-sortable-tree';

// Or you can import the tree without the dnd context as a named export. eg
import { SortableTreeWithoutDndContext as SortableTree } from 'react-sortable-tree';

// Importing from cjs (default)
import SortableTree from 'react-sortable-tree/dist/index.cjs.js';
import SortableTree from 'react-sortable-tree';

// Importing from esm
import SortableTree from 'react-sortable-tree/dist/index.esm.js';

Usage

import React, { Component } from 'react';
import SortableTree from 'react-sortable-tree';
import 'react-sortable-tree/style.css'; // This only needs to be imported once in your app

export default class Tree extends Component {
  constructor(props) {
    super(props);

    this.state = {
      treeData: [{ title: 'Chicken', children: [{ title: 'Egg' }] }],
    };
  }

  render() {
    return (
      <div style={{ height: 400 }}>
        <SortableTree
          treeData={this.state.treeData}
          onChange={treeData => this.setState({ treeData })}
        />
      </div>
    );
  }
}

Data Helper Functions

Need a hand turning your flat data into nested tree data?
Want to perform add/remove operations on the tree data without creating your own recursive function?
Check out the helper functions exported from tree-data-utils.js.

• getTreeFromFlatData: Convert flat data (like that from a database) into nested tree data.
• getFlatDataFromTree: Convert tree data back to flat data.
• addNodeUnderParent: Add a node under the parent node at the given path.
• removeNode: For a given path, get the node at that path, treeIndex, and the treeData with that node removed.
• removeNodeAtPath: For a given path, remove the node and return the treeData.
• changeNodeAtPath: Modify the node object at the given path.
• map: Perform a change on every node in the tree.
• walk: Visit every node in the tree in order.
• getDescendantCount: Count how many descendants this node has.
• getVisibleNodeCount: Count how many visible descendants this node has.
• getVisibleNodeInfoAtIndex: Get the th visible node in the tree data.
• toggleExpandedForAll: Expand or close every node in the tree.
• getNodeAtPath: Get the node at the input path.
• insertNode: Insert the input node at the specified depth and minimumTreeIndex.
• find: Find nodes matching a search query in the tree.
• isDescendant: Check if a node is a descendant of another node.
• getDepth: Get the longest path in the tree.

Themes

Using the theme prop along with an imported theme module, you can easily override the default appearance with another standard one.

Featured themes

File Explorer	Full Node Drag	Minimalistic theme inspired from MATERIAL UI

Help Wanted - As the themes feature has just been enabled, there are very few (only two at the time of this writing) theme modules available. If you've customized the appearance of your tree to be especially cool or easy to use, I would be happy to feature it in this readme with a link to the Github repo and NPM page if you convert it to a theme. You can use my file explorer theme repo as a template to plug in your own stuff.

Browser Compatibility

Troubleshooting

If it throws "TypeError: fn is not a function" errors in production

This issue may be related to an ongoing incompatibility between UglifyJS and Webpack's behavior. See an explanation at create-react-app#2376.

The simplest way to mitigate this issue is by adding comparisons: false to your Uglify config as seen here: https://github.com/facebookincubator/create-react-app/pull/2379/files

If it doesn't work with other components that use react-dnd

react-dnd only allows for one DragDropContext at a time (see: https://github.com/gaearon/react-dnd/issues/186). To get around this, you can import the context-less tree component via SortableTreeWithoutDndContext.

// before
import SortableTree from 'react-sortable-tree';

// after
import { SortableTreeWithoutDndContext as SortableTree } from 'react-sortable-tree';
