# vue-draggable-plus

[中文文档](https://alfred-skyblue.gitee.io/vue-draggable-plus/)

Drag and drop sorting module, support Vue>=v3 or Vue>=2.7

[Example of use](https://stackblitz.com/edit/github-b2xatc-qe8qxj?file=src%2FApp.vue)

## Describe

Since the `vue3` component of `Sortablejs` has not been updated, it has been seriously out of touch with `vue3`, so this project was born. This component is based on `Sortablejs`, so if you want to know more about `Sortablejs`, you can check it out [`Sortablejs` official website](https://github.com/SortableJS/Sortable)

We have encapsulated a variety of usages for this, you can use components, function, or instructions, there is always one that suits you

## Solve pain points

In `Sortablejs` official `Vue` components in the past, the drag-and-drop list is implemented by using the component as a direct child element of the list. When we use some component libraries, if there is no slot for the root element of the list in the component library , it is difficult for us to implement a drag list, vue-draggable-plus perfectly solves this problem, it allows you to use a drag list on any element, we can use the selector of the specified element to get the root element of the list, and then Use the root element of the list as `container` of `Sortablejs`, for details, refer to [specify target container](/demo/target-container/).

## Install

```bash

npm install vue-draggable-plus

```

## Usage

### Component usage

```vue



{{ item.name }}

import { ref } from 'vue'
import { VueDraggable } from 'vue-draggable-plus'

const list = ref([
{
name: 'Joao',
id: 1
},
{
name: 'Jean',
id: 2
},
{
name: 'Johanna',
id: 3
},
{
name: 'Juan',
id: 4
}
])

```

### Function Usage

```vue



{{ item.name }}

import { ref } from 'vue'
import { useDraggable } from 'vue-draggable-plus'

const el = ref<HTMLElement | null>(null)
const list = ref([
{
name: 'Joao',
id: 1
},
{
name: 'Jean',
id: 2
},
{
name: 'Johanna',
id: 3
},
{
name: 'Juan',
id: 4
}
])
// The return value is an object, which contains some methods, such as start, destroy, pause, etc.
const draggable = useDraggable(el, list, {
animation: 150,
onStart() {
console.log('start')
},
onUpdate() {
console.log('update')
}
})

```

### Directive Usage

```vue



{{ item.name }}

import { ref } from 'vue'
import { vDraggable } from 'vue-draggable-plus'
const list = ref([
{
name: 'Joao',
id: 1
},
{
name: 'Jean',
id: 2
},
{
name: 'Johanna',
id: 3
},
{
name: 'Juan',
id: 4
}
])

function onStart() {
console.log('start')
}

function onUpdate() {
console.log('update')
}

```

## Explanation

All event functions starting with `on` can be passed to components using `v-on`. For example:

```vue

import { ref } from "vue";
import { VueDraggable } from 'vue-draggable-plus'
import { SortableEvent } from "sortablejs";

const list = ref([
{
name: 'Joao',
id: '1'
},
{
name: 'Jean',
id: '2'
},
{
name: 'Johanna',
id: '3'
},
{
name: 'Juan',
id: '4'
}
])

function onStart(event: SortableEvent) {
console.log('start drag')
}

function onEnd(event: SortableEvent) {
console.log('end drag')
}

```

> For information on using Hooks and directives, please refer to the documentation.

## Options

`Options` inherits all configuration items from `Sortablejs`. For details, please see the [`Sortablejs` official documentation](https://github.com/SortableJS/Sortable).

### Types
```ts
type Easing =
| 'steps(int, start | end)'
| 'cubic-bezier(n, n, n, n)'
| 'linear'
| 'ease'
| 'ease-in'
| 'ease-out'
| 'ease-in-out'
| 'step-start'
| 'step-end'
| 'initial'
| 'inherit'

type PullResult = ReadonlyArray | boolean | 'clone';
type PutResult = ReadonlyArray | boolean;

interface GroupOptions {
/**
* Group name.
*/
name: string;
/**
* The ability to move from the list. Clone - copy the item instead of moving it.
*/
pull?: PullResult | ((to: Sortable, from: Sortable, dragEl: HTMLElement, event: SortableEvent) => PullResult) | undefined;
/**
* Whether elements can be added from other lists, or an array of group names from which elements can be obtained.
*/
put?: PutResult | ((to: Sortable, from: Sortable, dragEl: HTMLElement, event: SortableEvent) => PutResult) | undefined;
/**
* After moving to another list, the cloned element is restored to its initial position.
*/
revertClone?: boolean | undefined;
}

type Group = string | GroupOptions | undefined;

type ScrollFn = ((
this: Sortable,
offsetX: number,
offsetY: number,
originalEvent: Event,
touchEvt: TouchEvent,
hoverTargetEl: HTMLElement,
) => 'continue' | void) | undefined;
```
