react-html5-sortable

React mixin for HTML5 drag-and-drop sorting of items in a container

Demo

Installation

npm install --save react-html5-sortable

Setup

Use this library as a mixin into your list item components. Your list item component should have a reactKey prop which is the unique, unchanging, key for the item. When a list item is dragged over another list item, the onMove(src, dest) event will fire, which you can handle in your list component to change the data and re-render the list. src will be the reactKey prop for the list item being dragged, and dest will be the reactKey prop for the list item that the src item is above.

The example below uses a simple array of strings, but as long as your list item components have a reactKey prop, you can sort arrays of complex data structures with this module.

If your list item component has a dragHandle ref, that element will be the only part of the item that can be grabbed to drag the item. If dragHandle doesn't exist, the entire object can be grabbed.

Example

var Sortable = require("react-html5-sortable");

var MyListItem = React.createClass({
	mixins: [Sortable],
	render: function() {
		return <div>{this.props.text}</div>;
	}
});

var MyList = React.createClass({
	render: function() {
		var items = this.props.items.map(function(item) {
			return <MyListItem key={item} reactKey={item} text={item} onMove={this.props.onMove} />;
		}.bind(this));
		return <div>{items}</div>;
	}
});

var items = ["First Item", "Second Item", "Third Item", "Fourth Item", "Fifth Item"];

// If you're using [Flux](https://facebook.github.io/flux/), this would probably live in your Store
function move(src, dest) {
	var srcIdx = items.indexOf(src);
	var destIdx = items.indexOf(dest);
	if (srcIdx === -1 || destIdx === -1 || srcIdx === destIdx) {
		return;
	}
	var item = items.splice(srcIdx, 1);
	items.splice(destIdx, 0, item[0]);
	render();
}

function render() {
	React.render(<MyList items={items} onMove={move} />, document.getElementById("list-demo"));
}

render();
