Getting Started

Install with NPM:

bash
npm install sortablejs --save

Install with Bower:

bash
bower install --save sortablejs

Import into your project:

js
// Default SortableJS
import Sortable from 'sortablejs';

// Core SortableJS (without default plugins)
import Sortable from 'sortablejs/modular/sortable.core.esm.js';

// Complete SortableJS (with all plugins)
import Sortable from 'sortablejs/modular/sortable.complete.esm.js';

Cherrypick plugins:

js
// Cherrypick extra plugins
import Sortable, { MultiDrag, Swap } from 'sortablejs';

Sortable.mount(new MultiDrag(), new Swap());


// Cherrypick default plugins
import Sortable, { AutoScroll } from 'sortablejs/modular/sortable.core.esm.js';

Sortable.mount(new AutoScroll());

Usage

html

	item 1
	item 2
	item 3

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

You can use any element for the list and its elements, not just ul/li. Here is an example with divs.

		// same properties as onEnd
	}
});

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|["foo", "bar"]|'clone'|function — ability to move from the list. clone — copy the item, rather than move. Or an array of group names which the elements may be put in. Defaults to true.
* put: true|false|["baz", "qux"]|function — whether elements can be added from other lists, or an array of group names from which elements can be added.
* revertClone: boolean — revert cloned element to initial position after moving to a another list.

Demo:
- https://jsbin.com/hijetos/edit?js,output
- https://jsbin.com/nacoyah/edit?js,output — use of complex logic in the pull and put
- https://jsbin.com/bifuyab/edit?js,output — use revertClone: true

---

sort option

Allow sorting inside list.

Demo: https://jsbin.com/jayedig/edit?js,output

---

delay option

Time in milliseconds to define when the sorting should start. Unfortunately, due to browser restrictions, delaying is not possible on IE or Edge with native drag & drop.

Demo: https://jsbin.com/zosiwah/edit?js,output

---

delayOnTouchOnly option

Whether or not the delay should be applied only if the user is using touch (eg. on a mobile device). No delay will be applied in any other case. Defaults to false.

---

swapThreshold option

Percentage of the target that the swap zone will take up, as a float between 0 and 1.

Demo: http://sortablejs.github.io/Sortable#thresholds

---

invertSwap option

Set to true to set the swap zone to the sides of the target, for the effect of sorting "in between" items.

Read more

Demo: http://sortablejs.github.io/Sortable#thresholds

---

invertedSwapThreshold option

Percentage of the target that the inverted swap zone will take up, as a float between 0 and 1. If not given, will default to swapThreshold.

---

direction option

Direction that the Sortable should sort in. Can be set to 'vertical', 'horizontal', or a function, which will be called whenever a target is dragged over. Must return 'vertical' or 'horizontal'.

Read more

Example of direction detection for vertical list that includes full column and half column elements:

js
Sortable.create(el, {
	direction: function(evt, target, dragEl) {
		if (target !== null && target.className.includes('half-column') && dragEl.className.includes('half-column')) {
			return 'horizontal';
		}
		return 'vertical';
	}
});

---

touchStartThreshold option

This option is similar to fallbackTolerance option.

When the delay option is set, some phones with very sensitive touch displays like the Samsung Galaxy S8 will fire
unwanted touchmove events even when your finger is not moving, resulting in the sort not triggering.

This option sets the minimum pointer movement that must occur before the delayed sorting is cancelled.

Values between 3 to 5 are good.

---

disabled options

Disables the sortable if set to true.

Demo: https://jsbin.com/sewokud/edit?js,output

js
var sortable = Sortable.create(list);

document.getElementById("switcher").onclick = function () {
	var state = sortable.option("disabled"); // get

	sortable.option("disabled", !state); // set
};

---

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.

Demo: https://jsbin.com/numakuh/edit?html,js,output

js
Sortable.create(el, {
	handle: ".my-handle"
});

html

	:: list item text one
	:: list item text two

css
.my-handle {
	cursor: move;
	cursor: -webkit-grabbing;
}

---

filter option

js
Sortable.create(list, {
	filter: ".js-remove, .js-edit",
	onFilter: function (evt) {
		var item = evt.item,
			ctrl = evt.target;

		if (Sortable.utils.is(ctrl, ".js-remove")) {  // Click on remove button
			item.parentNode.removeChild(item); // remove sortable item
		}
		else if (Sortable.utils.is(ctrl, ".js-edit")) {  // Click on edit link
			// ...
		}
	}
})

---

ghostClass option

Class name for the drop placeholder (default sortable-ghost).

Demo: https://jsbin.com/henuyiw/edit?css,js,output

css
.ghost {
  opacity: 0.4;
}

js
Sortable.create(list, {
  ghostClass: "ghost"
});

---

chosenClass option

Class name for the chosen item (default sortable-chosen).

Demo: https://jsbin.com/hoqufox/edit?css,js,output

css
.chosen {
  color: #fff;
  background-color: #c00;
}

js
Sortable.create(list, {
  delay: 500,
  chosenClass: "chosen"
});

---

forceFallback option

If set to true, the Fallback for non HTML5 Browser will be used, even if we are using an HTML5 Browser. This gives us the possibility to test the behaviour for older Browsers even in newer Browser, or make the Drag 'n Drop feel more consistent between Desktop , Mobile and old Browsers.

On top of that, the Fallback always generates a copy of that DOM Element and appends the class fallbackClass defined in the options. This behaviour controls the look of this 'dragged' Element.

Demo: https://jsbin.com/sibiput/edit?html,css,js,output

---

fallbackTolerance option

Emulates the native drag threshold. Specify in pixels how far the mouse should move before it's considered as a drag. Useful if the items are also clickable like in a list of links.

When the user clicks inside a sortable element, it's not uncommon for your hand to move a little between the time you press and the time you release.
Dragging only starts if you move the pointer past a certain tolerance, so that you don't accidentally start dragging every time you click.

3 to 5 are probably good values.

---

dragoverBubble option

If set to true, the dragover event will bubble to parent sortables. Works on both fallback and native dragover event. By default, it is false, but Sortabl
