React Reorder (v2)

Drag & drop, touch enabled, reorder / sortable list, React component

If you are using v3 alpha, please refer to this documentation.

About

React Reorder is a React component that allows the user to drag-and-drop items in a list (horizontal / vertical) or a grid.

It fully supports touch devices and auto-scrolls when a component is being dragged (check out the demo, link below).

It also allows the user to set a hold time (duration before drag begins) allowing additional events like clicking / tapping to be applied.

Although this project is very new, it has been thoroughly tested in all modern browsers (see supported browsers).

Demo

Installation

• Using npm

  npm install react-reorder
  

  Add --save or -S to update your package.json

• Using bower

  bower install react-reorder
  

  Add --save or -S to update your bower.json

Example

1. If using requirejs: add react-reorder to your require.config

   paths:
     // <name> : <path/to/module>
     'react-reorder': 'react-reorder/reorder'
   }
   

2. If using a module loader (requirejs / browserfiy / commonjs): require react-reorder where it will be used in your project

   var Reorder = require('react-reorder');
   

   If using requirejs you'll probably want to wrap your module e.g.

   define(function (require) {
     // Require react-reorder here
   });
   

3. Configuration

   Note: If your array is an array of primitives (e.g. strings) then itemKey is not required as the string itself will be used as the key, however item keys must be unique in any case

   1. Using JSX

      <Reorder
        // The key of each object in your list to use as the element key
        itemKey='name'
        // Lock horizontal to have a vertical list
        lock='horizontal'
        // The milliseconds to hold an item for before dragging begins
        holdTime='500'
        // The list to display
        list={[
          {name: 'Item 1'},
          {name: 'Item 2'},
          {name: 'Item 3'}
        ]}
        // A template to display for each list item
        template={ListItem}
        // Function that is called once a reorder has been performed
        callback={this.callback}
        // Class to be applied to the outer list element
        listClass='my-list'
        // Class to be applied to each list item's wrapper element
        itemClass='list-item'
        // A function to be called if a list item is clicked (before hold time is up)
        itemClicked={this.itemClicked}
        // The item to be selected (adds 'selected' class)
        selected={this.state.selected}
        // The key to compare from the selected item object with each item object
        selectedKey='uuid'
        // Allows reordering to be disabled
        disableReorder={false}
      />
      

   2. Using standard Javascript

      React.createElement(Reorder, {
        // The key of each object in your list to use as the element key
        itemKey: 'name',
        // Lock horizontal to have a vertical list
        lock: 'horizontal',
        // The milliseconds to hold an item for before dragging begins
        holdTime: '500',
        // The list to display
        list: [
          {name: 'Item 1'},
          {name: 'Item 2'},
          {name: 'Item 3'}
        ],
        // A template to display for each list item
        template: ListItem,
        // Function that is called once a reorder has been performed
        callback: this.callback,
        // Class to be applied to the outer list element
        listClass: 'my-list',
        // Class to be applied to each list item's wrapper element
        itemClass: 'list-item',
        // A function to be called if a list item is clicked (before hold time is up)
        itemClicked: this.itemClicked,
        // The item to be selected (adds 'selected' class)
        selected: this.state.selected,
        // The key to compare from the selected item object with each item object
        selectedKey: 'uuid',
        // Allows reordering to be disabled
        disableReorder: false
      })
      

4. Callback functions

   1. The callback function that is called once a reorder has been performed

      function callback(event, itemThatHasBeenMoved, itemsPreviousIndex, itemsNewIndex, reorderedArray) {
        // ...
      }
      

   2. The itemClicked function that is called when an item is clicked before any dragging begins

      function itemClicked(event, itemThatHasBeenClicked, itemsIndex) {
        // ...
      }
      

      Note: event will be the synthetic React event for either mouseup or touchend, and both contain clientX & clientY values (for ease of use)
