react-easy-sort

A React component to sort items in lists or grids

The goal of this component is to allow sorting elements with drag and drop.

It is mobile friendly by default. It doesn't block scrolling the page when swiping inside it: the user needs to press an item during at least 200ms to start the drag gesture.

On non-touch device, the drag gesture only starts after moving an element by at least one pixel. This is done to avoid blocking clicks on clickable elements inside an item.

Features

• Supports horizontal and vertical lists
• Supports grid layouts
• Mobile-friendly
• IE11 support 🙈

Installation

Basic usage

import SortableList, { SortableItem } from 'react-easy-sort'
import arrayMove from 'array-move'

const App = () => {
  const [items, setItems] = React.useState(['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I'])

  const onSortEnd = (oldIndex: number, newIndex: number) => {
    setItems((array) => arrayMove(array, oldIndex, newIndex))
  }

  return (
    <SortableList onSortEnd={onSortEnd} className="list" draggedItemClassName="dragged">
      {items.map((item) => (
        <SortableItem key={item}>
          <div className="item">{item}</div>
        </SortableItem>
      ))}
    </SortableList>

SortableItem

This component doesn't take any other props than its child. This child should be a single React element that can receives a ref. If you pass a component as a child, it needs to be wrapped with React.forwardRef().

SortableKnob

You can use this component if you doesn't want to whole item to be draggable but only a specific area of it.

import SortableList, { SortableItem, SortableKnob } from 'react-easy-sort'
import arrayMove from 'array-move'

const App = () => {
  const [items, setItems] = React.useState(['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I'])

  const onSortEnd = (oldIndex: number, newIndex: number) => {
    setItems((array) => arrayMove(array, oldIndex, newIndex))
  }

  return (
    <SortableList onSortEnd={onSortEnd} className="list" draggedItemClassName="dragged">
      {items.map((item) => (
        <SortableItem key={item}>
          <div className="item">
            <SortableKnob>
              <div>Drag me</div>
            </SortableKnob>
            {item}
          </div>
        </SortableItem>
      ))}
    </SortableList>
  )
}

Recommended CSS rules

To disable browser default behaviors than can interfer with the dragging experience, we recommend adding the following declarations on the "items":

• user-select: none;: disable the selection of content inside the item (the blue box)
• pointer-events: none;: required for some browsers if your items contain images (see the Interactive avatars demo)

• https://github.com/atlassian/react-beautiful-dnd: another great library for sorting items. However, it doesn't support grid layouts (as of 2021-02-05).
