A set of higher-order components to turn any list into an animated, touch-friendly, sortable list.

Examples available here: http://clauderic.github.io/react-sortable-hoc/

Features

• Higher Order Components – Integrates with your existing components
• Drag handle, auto-scrolling, locked axis, events, and more!
• Suuuper smooth animations – Chasing the 60FPS dream 🌈
• Works with virtualization libraries: react-virtualized, react-tiny-virtual-list, react-infinite, etc.
• Horizontal lists, vertical lists, or a grid ↔ ↕ ⤡
• Touch support 👌
• Accessible: supports keyboard sorting

Installation

Using npm:

$ npm install react-sortable-hoc --save

Then, using a module bundler that supports either CommonJS or ES2015 modules, such as webpack:

// Using an ES6 transpiler like Babel
import {SortableContainer, SortableElement} from 'react-sortable-hoc';
 
// Not using an ES6 transpiler
var Sortable = require('react-sortable-hoc');
var SortableContainer = Sortable.SortableContainer;
var SortableElement = Sortable.SortableElement;

Alternatively, an UMD build is also available:

<script src="react-sortable-hoc/dist/umd/react-sortable-hoc.js"></script>

Usage

Basic Example

import React, {Component} from 'react';
import {render} from 'react-dom';
import {SortableContainer, SortableElement} from 'react-sortable-hoc';
import arrayMove from 'array-move';
 
const SortableItem = SortableElement(({value}) => <li>{value}</li>);
 
const SortableList = SortableContainer(({items}) => {
  return (
    <ul>
      {items.map((value, index) => (
        <SortableItem key={`item-${index}`} index={index} value={value} />
      ))}
    </ul>
  );
});
 
class SortableComponent extends Component {
  state = {
    items: ['Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5', 'Item 6'],
  };
  onSortEnd = ({oldIndex, newIndex}) => {
    this.setState(({items}) => ({
      items: arrayMove(items, oldIndex, newIndex),
    }));
  };
  render() {
    return <SortableList items={this.state.items} onSortEnd={this.onSortEnd} />;
  }
}
 
render(<SortableComponent />, document.getElementById('root'));

That's it! React Sortable does not come with any styles by default, since it's meant to enhance your existing components.

Why should I use this?

There are already a number of great Drag & Drop libraries out there (for instance, react-dnd is fantastic). If those libraries fit your needs, you should definitely give them a try first. However, most of those libraries rely on the HTML5 Drag & Drop API, which has some severe limitations. For instance, things rapidly become tricky if you need to support touch devices, if you need to lock dragging to an axis, or want to animate the nodes as they're being sorted. React Sortable HOC aims to provide a simple set of higher-order components to fill those gaps. If you're looking for a dead-simple, mobile-friendly way to add sortable functionality to your lists, then you're in the right place.

Prop Types

SortableContainer HOC

* OffsetValue can either be a finite Number or a String made up of a number and a unit (px or %). Examples: 10 (which is the same as "10px"), "50%"

SortableElement HOC

FAQ

Running Examples

In root folder, run the following commands to launch React Storybook:

$ npm install
$ npm start

Accessibility

React Sortable HOC supports keyboard sorting out of the box. To enable it, make sure your SortableElement or SortableHandle is focusable. This can be done by setting tabIndex={0} on the outermost HTML node rendered by the component you're enhancing with SortableElement or SortableHandle.

Once an item is focused/tabbed to, pressing SPACE picks it up, ArrowUp or ArrowLeft moves it one place backward in the list, ArrowDown or ArrowRight moves items one place forward in the list, pressing SPACE again drops the item in its new position. Pressing ESC before the item is dropped will cancel the sort operations.

Grid support

Need to sort items in a grid? We've got you covered! Just set the axis prop to xy. Grid support is currently limited to a setup where all the cells in the grid have the same width and height, though we're working hard to get variable width support in the near future.

Item disappearing when sorting / CSS issues

Upon sorting, react-sortable-hoc creates a clone of the element you are sorting (the sortable-helper) and appends it to the end of the <body> tag. The original element will still be in-place to preserve its position in the DOM until the end of the drag (with inline-styling to make it invisible). If the sortable-helper gets messed up from a CSS standpoint, consider that maybe your selectors to the draggable item are dependent on a parent element which isn't present anymore (again, since the sortable-helper is at the end of the <body>). This can also be a z-index issue, for example, when using react-sortable-hoc within a Bootstrap modal, you'll need to increase the z-index of the SortableHelper so it is displayed on top of the modal (see #87 for more details).

Click events being swallowed

By default, react-sortable-hoc is triggered immediately on mousedown. If you'd like to prevent this behaviour, there are a number of strategies readily available. You can use the distance prop to set a minimum distance (in pixels) to be dragged before sorting is enabled. You can also use the pressDelay prop to add a delay before sorting is enabled. Alternatively, you can also use the SortableHandle HOC.

Wrapper props not passed down to wrapped Component

All props for SortableContainer and SortableElement listed above are intentionally consumed by the wrapper component and are not passed down to the wrapped component. To make them available pass down the desired prop again with a different name. E.g.:

const SortableItem = SortableElement(({value, sortIndex}) => (
  <li>
    {value} - #{sortIndex}
  </li>
));
 
const SortableList = SortableContainer(({items}) => {
  return (
    <ul>
      {items.map((value, index) => (
        <SortableItem
          key={`item-${index}`}
          index={index}
          sortIndex={index}
          value={value}
        />
      ))}
    </ul>
  );
});

Dependencies

React Sortable HOC only depends on invariant. It has the following peerDependencies: react, react-dom
