<draggable 
  v-model="myArray" 
  group="people" 
  @start="drag=true" 
  @end="drag=false" 
  item-key="id">
  <template #item="{element}">
    <div>{{element.name}}</div>
   </template>
</draggable>

  import draggable from 'vuedraggable'
  ...
  export default {
        components: {
            draggable,
        },
        data() {
          return {
            drag: false,
          }
        },
  ...

The item slot should be used to display items of the list. It receives the element value and the element index as slot-props.

<draggable v-model="myArray" tag="transition-group" item-key="id">
  <template #item="{element}">
      <div> {{element.name}} </div>
  </template>
</draggable>

<draggable v-model="myArray" item-key="id">
  <template #item="{element}">
    <div> {{element.name}} </div>
  </template>
  <template #footer>
    <button @click="addPeople">Add</button>
  </template>
</draggable>

<draggable v-model="myArray" item-key="id">
  <template #item="{element}">
    <div> {{element.name}} </div>
  </template>
  <template #header>
    <button @click="addPeople">Add</button>
  </template>
</draggable>

<draggable v-model='myList'>

computed: {
    myList: {
        get() {
            return this.$store.state.myList
        },
        set(value) {
            this.$store.commit('updateList', value)
        }
    }
}

Breaking changes:

1. Use item slot instead of default to display elements
2. Provide a key for items using itemKey props

From:

<!-- vue 2 version -->
<draggable v-model="myArray">
   <div v-for="element in myArray" :key="element.id">{{element.name}}</div>
</draggable>

To:

<draggable v-model="myArray" item-key="id">
  <template #item="{element}">
    <div>{{element.name}}</div>
   </template>
</draggable>

Breaking changes: 3) When using transition, you should now use the tag props and componentData to create the transition

From

<!-- vue 2 version -->
<draggable v-model="myArray">
    <transition-group name="fade">
        <div v-for="element in myArray" :key="element.id">
            {{element.name}}
        </div>
    </transition-group>
</draggable>

to

<draggable v-model="myArray" tag="transition-group" :component-data="{name:'fade'}">
  <template #item="{element}">
    <div>{{element.name}}</div>
  </template>
</draggable>

Type: Array
Required: false
Default: null

Input array to draggable component. Typically same array as referenced by inner element v-for directive.
This is the preferred way to use Vue.draggable as it is compatible with Vuex.
It should not be used directly but only though the v-model directive:

<draggable v-model="myArray">

Type: Array
Required: false
Default: null

Alternative to the modelValue prop, list is an array to be synchronized with drag-and-drop.
The main difference is that list prop is updated by draggable component using splice method, whereas modelValue is immutable.
Do not use in conjunction with modelValue prop.

Type: String or Function
Required: true

The property to be used as the element key. Alternatively a function receiving an element of the list and returning its key.

Sortable options can be set directly as vue.draggable props since version 2.19.

This means that all sortable option are valid sortable props with the notable exception of all the method starting by "on" as draggable component expose the same API via events.

kebab-case property are supported: for example ghost-class props will be converted to ghostClass sortable option.

Example setting handle, sortable and a group option:

<draggable
        v-model="list"
        handle=".handle"
        :group="{ name: 'people', pull: 'clone', put: false }"
        ghost-class="ghost"
        :sort="false"
        @change="log"
      >
      <!-- -->
</draggable>

Type: String
Default: 'div'

HTML node type of the element that draggable component create as outer element for the included slot.
It is also possible to pass the name of vue component as element. In this case, draggable attribute will be passed to the create component.
See also componentData if you need to set props or event to the created component.

Type: Function
Required: false
Default: (original) => { return original;}

Function called on the source component to clone element when clone option is true. The unique argument is the viewModel element to be cloned and the returned value is its cloned version.
By default vue.draggable reuses the viewModel element, so you have to use this hook if you want to clone or deep clone it.

Type: Function
Required: false
Default: null

If not null this function will be called in a similar way as Sortable onMove callback. Returning false will cancel the drag operation.

function onMoveCallback(evt, originalEvent){
   ...
    // return false; — for cancel
}

evt object has same property as Sortable onMove event, and 3 additional properties:

• draggedContext: context linked to dragged element
  • index: dragged element index
  • element: dragged element underlying view model element
  • futureIndex: potential index of the dragged element if the drop operation is accepted
• relatedContext: context linked to current drag operation
  • index: target element index
  • element: target element view model element
  • list: target list
  • component: target VueComponent

HTML:

<draggable :list="list" :move="checkMove">

javascript:

checkMove: function(evt){
    return (evt.draggedContext.element.name!=='apple');
}

See complete example: Cancel.html, cancel.js

Type: Object
Required: false
Default: null

This props is used to pass additional information to child component declared by tag props.
Value: an object corresponding to the attributes, props and events we would pass to the component.

Example (using element UI library):

<draggable tag="el-collapse" :list="list" :component-data="getComponentData()" item-key="name">
  <template #item="{element}">
    <el-collapse-item :title="element.title" :name="element.name">
        <div>{{element.description}}</div> 
     </el-collapse-item>
  </template>
</draggable>

methods: {
    handleChange() {
      console.log('changed');
    },
    inputChanged(value) {
      this.activeNames = value;
    },
    getComponentData() {
      return {
        onChange: this.handleChange,
        onInput: this.inputChanged,
        wrap: true,
        value: this.activeNames
      };
    }
  }

• Support for Sortable events:

  start, add, remove, update, end, choose, unchoose, sort, filter, clone
  Events are called whenever onStart, onAdd, onRemove, onUpdate, onEnd, onChoose, onUnchoose, onSort, onClone are fired by Sortable.js with the same argument.
  See here for reference

  Note that SortableJS OnMove callback is mapped with the move prop

HTML:

<draggable :list="list" @end="onEnd">

• change event

  change event is triggered when list prop is not null and the corresponding array is altered due to drag-and-drop operation.
  This event is called with one argument containing one of the following properties:

  • added: contains information of an element added to the array
    • newIndex: the index of the added element
    • element: the added element
  • removed: contains information of an element removed from to the array
    • oldIndex: the index of the element before remove
    • element: the removed element
  • moved: contains information of an element moved within the array
    • newIndex: the current index of the moved element
    • oldIndex: the old index of the moved element
    • element: the moved element

The item slot is used to display one element of the list. Vue.draggable will iterate the list and call this slot for each element.

Slot props:

• element the element in the list
• index the element index

It is the only required slot.

<draggable v-model="myArray" item-key="id">
  <template #item="{element, index}">
    <div> {{index}} - {{element.name}} </div>
  </template>
</draggable>

Use the header slot to add none-draggable element inside the vuedraggable component. Ex:

<draggable v-model="myArray" item-key="id">
  <template #item="{element}">
    <div> {{element.name}} </div>
  </template>
  <template #header>
    <button @click="addPeople">Add</button>
  </template>
</draggable>

Use the footer slot to add none-draggable element inside the vuedraggable component. Ex:

<draggable v-model="myArray" item-key="id">
  <template #item="{element}">
    <div> {{element.name}} </div>
  </template>
  <template #footer>
    <button @click="addPeople">Add</button>
  </template>
</draggable>
