What is vuedraggable?
vuedraggable is a Vue.js component that allows you to create draggable and sortable lists with ease. It is based on the Sortable.js library and provides a simple way to implement drag-and-drop functionality in your Vue applications.
What are vuedraggable's main functionalities?
Basic Draggable List
This code sample demonstrates a basic draggable list using vuedraggable. The list items can be dragged and reordered.
<template>
<draggable v-model="items">
<div v-for="item in items" :key="item.id">{{ item.name }}</div>
</draggable>
</template>
<script>
import draggable from 'vuedraggable';
export default {
components: { draggable },
data() {
return {
items: [
{ id: 1, name: 'Item 1' },
{ id: 2, name: 'Item 2' },
{ id: 3, name: 'Item 3' }
]
};
}
};
</script>
Draggable with Handle
This code sample shows how to use a handle for dragging items. Only the handle (represented by '::') can be used to drag the items.
<template>
<draggable v-model="items" handle=".handle">
<div v-for="item in items" :key="item.id">
<span class="handle">::</span> {{ item.name }}
</div>
</draggable>
</template>
<script>
import draggable from 'vuedraggable';
export default {
components: { draggable },
data() {
return {
items: [
{ id: 1, name: 'Item 1' },
{ id: 2, name: 'Item 2' },
{ id: 3, name: 'Item 3' }
]
};
}
};
</script>
Nested Draggable Lists
This code sample demonstrates how to create nested draggable lists. Both parent and child items can be dragged and reordered independently.
<template>
<draggable v-model="parentItems">
<div v-for="parent in parentItems" :key="parent.id">
<div>{{ parent.name }}</div>
<draggable v-model="parent.children">
<div v-for="child in parent.children" :key="child.id">{{ child.name }}</div>
</draggable>
</div>
</draggable>
</template>
<script>
import draggable from 'vuedraggable';
export default {
components: { draggable },
data() {
return {
parentItems: [
{ id: 1, name: 'Parent 1', children: [
{ id: 11, name: 'Child 1' },
{ id: 12, name: 'Child 2' }
]},
{ id: 2, name: 'Parent 2', children: [
{ id: 21, name: 'Child 3' },
{ id: 22, name: 'Child 4' }
]}
]
};
}
};
</script>
Other packages similar to vuedraggable
vue-slicksort
vue-slicksort is a set of higher-order components for building sortable interfaces. It is inspired by react-sortable-hoc and provides similar functionality to vuedraggable, but with a different API and additional features like horizontal sorting and grid layouts.
vue-draggable-resizable
vue-draggable-resizable is a Vue component that allows you to create draggable and resizable elements. While it focuses more on resizable functionality, it also provides drag-and-drop capabilities similar to vuedraggable.
vue-grid-layout
vue-grid-layout is a grid layout system for Vue.js, heavily inspired by React's Grid Layout. It allows for draggable and resizable grid items, making it suitable for creating complex, responsive layouts. It offers more advanced layout capabilities compared to vuedraggable.
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.
<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){
...
}
evt object has same property as Sortable onMove event, and 3 additional properties:
draggedContext
: context linked to dragged element
index
: dragged element indexelement
: dragged element underlying view model elementfutureIndex
: potential index of the dragged element if the drop operation is accepted
relatedContext
: context linked to current drag operation
index
: target element indexelement
: target element view model elementlist
: target listcomponent
: 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 componenton
: 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">
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.
