Getting Started

Install with NPM:

npm install sortablejs --save

Install with Bower:

bower install --save sortablejs

Import into your project:

// 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:

// 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

<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);

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

    forceFallback: false,  // ignore the HTML5 DnD behaviour and force the fallback to kick in

    fallbackClass: "sortable-fallback",  // Class name for the cloned DOM Element when using forceFallback
    fallbackOnBody: false,  // Appends the cloned DOM Element into the Document's Body
    fallbackTolerance: 0, // Specify in pixels how far the mouse should move before it's considered as a drag.

    dragoverBubble: false,
    removeCloneOnHide: true, // Remove the clone element when it is not showing, rather than just hiding it

    setData: function (/** DataTransfer */dataTransfer, /** HTMLElement*/dragEl) {
        dataTransfer.setData('Text', dragEl.textContent); // `dataTransfer` object of HTML5 DragEvent
    },

    // Element is chosen
    onChoose: function (/**Event*/evt) {
        evt.oldIndex;  // element index within parent
    },

    // Element is unchosen
    onUnchoose: function(/**Event*/evt) {
        // same properties as onEnd
    },

    // Element dragging started
    onStart: function (/**Event*/evt) {
        evt.oldIndex;  // element index within parent
    },

    // Element dragging ended
    onEnd: function (/**Event*/evt) {

        evt.clone // the clone element
        evt.pullMode;  // when item is in another sortable: `"clone"` if cloning, `true` if moving
    },

    // Element is dropped into the list from another list
    onAdd: function (/**Event*/evt) {
        // same properties as onEnd
    },

    // Changed sorting within list
    onUpdate: function (/**Event*/evt) {
        // same properties as onEnd
    },

    // Called by any change to the list (add / update / remove)
    onSort: function (/**Event*/evt) {
        // same properties as onEnd
    },

    // Element is removed from the list into another list
    onRemove: function (/**Event*/evt) {
        // same properties as onEnd
    },

    // Attempt to drag a filtered element
    onFilter: function (/**Event*/evt) {
        var itemEl = evt.item;  // HTMLElement receiving the `mousedown|tapstart` event.
    },

    // Event when you move an item in the list or between lists
    onMove: function (/**Event*/evt, /**Event*/originalEvent) {
        // Example: https://jsbin.com/nawahef/edit?js,output
        evt.dragged; // dragged HTMLElement
        evt.draggedRect; // DOMRect {left, top, right, bottom}
        evt.related; // HTMLElement on which have guided
        evt.relatedRect; // DOMRect
        evt.willInsertAfter; // Boolean that is true if Sortable will insert drag element after target by default
        originalEvent.clientY; // mouse position
        // return false; — for cancel
        // return -1; — insert before target
        // return 1; — insert after target
        // return true; — keep default insertion point based on the direction
        // return void; — keep default insertion point based on the direction
    },

    // Called when creating a clone of element
    onClone: function (/**Event*/evt) {
        var origEl = evt.item;
        var cloneEl = evt.clone;
    },

    // Called when dragging element changes position
    onChange: function(/**Event*/evt) {
        evt.newIndex // most likely why this event is used is to get the dragging element's current index
        // 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 andput - 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.

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:

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

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

Sortable.create(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;
    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
