Sortable

Sortable is a minimalist JavaScript library for reorderable drag-and-drop lists.

Demo: http://rubaxa.github.io/Sortable/

Features

• Supports touch devices and modern browsers
• Can drag from one list to another or within the same list
• Animation moving items when sorting (css animation)
• Supports drag handles and selectable text (better than voidberg's html5sortable)
• Built using native HTML5 drag and drop API
• Supports AngularJS and and any CSS library, e.g. Bootstrap
• Simple API
• No jQuery

Usage

<ul id="items">
	<li>item 1</li>
	<li>item 2</li>
	<li>item 3</li>
</ul>

var el = document.getElementById('items');
var sortable = Sortable.create(el);

---

Options

var sortabel = new Sortable(el, {
	group: "name", // or { name: "..", pull: [true, false, clone], put: [true, false, array] }
	sort: true, // sorting inside list
	store: null, // @see Store
	animation: 150, // ms, animation speed moving items when sorting, `0` — without animation
	handle: ".my-handle", // Drag handle selector within list items
	filter: ".ignor-elements", // Selectors that do not lead to dragging (String or Function)
	draggable: ".item",   // Specifies which items inside the element should be sortable
	ghostClass: "sortable-ghost",
	setData: function (dataTransfer, dragEl) {
		dataTransfer.setData('Text', dragEl.textContent);
	},

	onStart: function (/**Event*/evt) { /* dragging */ },
	onEnd: function (/**Event*/evt) { /* dragging */ },

	// Element is dropped into the list from another list
	onAdd: function (/**Event*/evt){
		var itemEl = evt.item; // dragged HTMLElement
		itemEl.from; // previous list
	},

	// Changed sorting within list
	onUpdate: function (/**Event*/evt){
		var itemEl = evt.item; // dragged HTMLElement
	},

	// Called by any change to the list (add / update / remove)
	onSort: function (/**Event*/evt){
		var itemEl = evt.item; // dragged HTMLElement
	},

	// Element is removed from the list into another list
	onRemove: function (/**Event*/evt){
		var itemEl = evt.item; // dragged HTMLElement
	},

	onFilter: function (/**Event*/evt){
		var itemEl = evt.item; // HTMLElement on which was `mousedown|tapstart` event.
	}
});

handle option

To make list items draggable, Sortable disables text selection by the user. That's not always desirable. To allow text selection, define a drag handler, which is an area of every list element that allows it to be dragged around.

var sortable = new Sortable(el, {
        handle: ".my-handle",
});

<ul>
	<li><span class="my-handle">::</span> list item text one
	<li><span class="my-handle">::</span> list item text two
</ul>

.my-handle {
	cursor: move
}

---

group option

To drag elements from one list into another, both lists must have the same group value. You can also define whether lists can give away, give and keep a copy (clone), and receive elements.

• name:string — group name
• pull:true|false|'clone' — ability to move from the list. clone — cloning drag item when moving from the list.
• put:true|false|["foo", "bar"] — the possibility of adding an element from the other list, or an array of names groups, which can be taken.

Support AngularJS

Include ng-sortable.js

Demo: http://jsbin.com/naduvo/1/edit?html,js,output

<div ng-app="myApp" ng-controller="demo">
	<ul ng-sortable>
		<li ng-repeat="item in items">{{item}}</li>
	</ul>

	<ul ng-sortable="{ group: 'foobar' }">
		<li ng-repeat="item in foo">{{item}}</li>
	</ul>

	<ul ng-sortable="barConfig">
		<li ng-repeat="item in bar">{{item}}</li>
	</ul>
</div>

angular.module('myApp', ['ng-sortable'])
	.controller('demo', ['$scope', function ($scope) {
		$scope.items = ['item 1', 'item 2'];
		$scope.foo = ['foo 1', '..'];
		$scope.bar = ['bar 1', '..'];
		$scope.barConfig = { group: 'foobar', animation: 150 };
	}]);

---

Method

option(name:String[, value:*]):*

Get or set the option.

closest(el:String[, selector:HTMLElement]):HTMLElement|null

For each element in the set, get the first element that matches the selector by testing the element itself and traversing up through its ancestors in the DOM tree.

var editableList = new Sortable(list, {
	filter: ".js-remove, .js-edit",
	onFilter: function (evt) {
		var el = editableList.closest(evt.item); // list item

		if (editableList.closest(evt.item, ".js-remove")) { // Click on remove button
			el.parentNode.removeChild(el); // remove sortable item
		}
		else if (editableList.closest(evt.item, ".js-edit")) { // Click on edit link
			// ...
		}
	}
})

toArray():String[]

Serializes the sortable's item data-id's into an array of string.

sort(order:String[])

Sorts the elements according to the array.

var order = sortable.toArray();
sortable.sort(order.reverse()); // apply

destroy()

Removes the sortable functionality completely.

---

Store

Saving and restoring of the sort.

<ul>
	<li data-id="1">order</li>
	<li data-id="2">save</li>
	<li data-id="3">restore</li>
</ul>

Sortable.create(el, {
	group: "localStorage-example",
	store: {
		/**
		 * Get the order of elements. Called once during initialization.
		 * @param   {Sortable}  sortable
		 * @retruns {Array}
		 */
		get: function (sortable) {
			var order = localStorage.getItem(sortable.options.group);
			return order ? order.split('|') : [];
		},

		/**
		 * Save the order of elements. Called every time at the drag end.
		 * @param {Sortable}  sortable
		 */
		set: function (sortable) {
			var order = sortable.toArray();
			localStorage.setItem(sortable.options.group, order.join('|'));
		}
	}
})
