Vue.Draggable

Vue component (Vue.js 2.0) or directive (Vue.js 1.0) allowing drag-and-drop and synchronization with view model array.

Based on and offering all features of Sortable.js

Demo

Features

Full support of Sortable.js features:
- Supports touch devices
- Supports drag handles and selectable text
- Smart auto-scrolling
- Support drag and drop between different lists
- No jQuery dependency
Keeps in sync HTML and view model list
Compatible with Vue.js 2.0 transition-group
Cancellation support
Events reporting any changes when full control is needed

For Vue.js 2.0

Use draggable component:

Typical use:

<draggable v-model="myArray" :options="{group:'people'}" @start="drag=true" @end="drag=false">
   <div v-for="element in myArray" :key="element.id">{{element.name}}</div>
</draggable>

.vue file:

  import draggable from 'vuedraggable'
  ...
  export default {
        components: {
            draggable,
        },
  ...

With `transition-group`:

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

Draggable component should directly wrap the draggable elements, or a transition-component containing the draggable elements.

With footer slot:

<draggable v-model="myArray" :options="{draggable:'.item'}">
    <div v-for="element in myArray" :key="element.id" class="item">
        {{element.name}}
    </div>
    <button slot="footer" @click="addPeople">Add</button>
</draggable>

With Vuex:

<draggable v-model='myList'>

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

Props

value

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">

list

Type: Array
Required: false
Default: null

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

options

Type: Object
Required: false

Option used to initialize the sortable object see: sortable option documentation
Note that all the method starting by "on" will be ignored as draggable component expose the same API via events.

element

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.

clone

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.

move

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

componentData

Type: Object
Required: false
Default: null

This props is used to pass additional information to child component declared by element props.
Value:

props: props to be passed to the child component
on: events to be subscribe in the child component

Example (using element UI library):

<draggable element="el-collapse" :list="list" :component-data="getComponentData()">
    <el-collapse-item v-for="e in list" :title="e.title" :name="e.name" :key="e.name">
        <div>{{e.description}}</div>
     </el-collapse-item>
</draggable>

methods: {
    handleChange() {
      console.log('changed');
    },
    inputChanged(value) {
      this.activeNames = value;
    },
    getComponentData() {
      return {
        on: {
          change: this.handleChange,
          input: this.inputChanged
        },
        props: {
          value: this.activeNames
        }
      };
    }
  }

Events

Support for Sortable events:

start, add, remove, update, end, choose, sort, filter, clone
Events are called whenever onStart, onAdd, onRemove, onUpdate, onEnd, onChoose, 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

Slots

Use the footer slot to add none-draggable element inside the vuedraggable component. Important: it should be used in conjunction with draggable option to tag draggable element. Note that footer slot will always be added after the default slot. Ex:

<draggable v-model="myArray" :options="{draggable:'.item'}">
    <div v-for="element in myArray" :key="element.id" class="item">
        {{element.name}}
    </div>
    <button slot="footer" @click="addPeople">Add</button>
</draggable>

Gotchas

Drag operation with empty list:

To be able to drag items on an empty draggable component, set a min-height greater than 0 on the draggable component or the transition-group if any and ensure the transition group has display: block; otherwise height won't work.
