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
<ulid="items">
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>
</ul>
```
```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 `div`s](https://jsbin.com/visimub/edit?html,js,output).
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` 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`.
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'`.
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.
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 Sortable will only stop bubbling the event once the element has been inserted into a parent Sortable, or *can* be inserted into a parent Sortable, but isn't at that specific time (due to animation, etc).
Since 1.8.0, you will probably want to leave this option as false. Before 1.8.0, it may need to be `true` for nested sortables to work.
---
#### `removeCloneOnHide` option
If set to `false`, the clone is hidden by having it's CSS `display` property set to `none`.
By default, this option is `true`, meaning Sortable will remove the cloned element from the DOM when it is supposed to be hidden.
---
#### `emptyInsertThreshold` option
The distance (in pixels) the mouse must be from an empty sortable while dragging for the drag element to be inserted into that sortable. Defaults to `5`. Set to `0` to disable this feature.
Demo: https://jsbin.com/becavoj/edit?js,output
An alternative to this option would be to set a padding on your list when it is empty.
For example:
```css
ul:empty {
padding-bottom: 20px;
}
```
Warning: For `:empty` to work, it must have no node inside (even text one).
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.
##### toArray():`String[]`
Serializes the sortable's item `data-id`'s (`dataIdAttr` option) into an array of string.
* on(el`:HTMLElement`, event`:String`, fn`:Function`) — attach an event handler function
* off(el`:HTMLElement`, event`:String`, fn`:Function`) — remove an event handler
* css(el`:HTMLElement`)`:Object` — get the values of all the CSS properties
* css(el`:HTMLElement`, prop`:String`)`:Mixed` — get the value of style properties
* css(el`:HTMLElement`, prop`:String`, value`:String`) — set one CSS properties
* css(el`:HTMLElement`, props`:Object`) — set more CSS properties
* find(ctx`:HTMLElement`, tagName`:String`[, iterator`:Function`])`:Array` — get elements by tag name
* bind(ctx`:Mixed`, fn`:Function`)`:Function` — Takes a function and returns a new one that will always have a particular context
* is(el`:HTMLElement`, selector`:String`)`:Boolean` — check the current matched set of elements against a selector
* closest(el`:HTMLElement`, selector`:String`[, ctx`: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
* clone(el`:HTMLElement`)`:HTMLElement` — create a deep copy of the set of matched elements
* toggleClass(el`:HTMLElement`, name`:String`, state`:Boolean`) — add or remove one classes from each element
* detectDirection(el`:HTMLElement`)`:String` — automatically detect the [direction](https://github.com/SortableJS/Sortable/wiki/Swap-Thresholds-and-Direction#direction) of the element as either `'vertical'` or `'horizontal'`
