Vue Slicksort 🖖
A set of component mixins to turn any list into an animated, touch-friendly, sortable list. Based on react-sortable-hoc by [@clauderic]
Examples available here: https://jexordexan.github.io/vue-slicksort/

v-model
Compatible – Make any array editable with thev-model
standard- Mixin Components – Integrates with your existing components
- Standalone Components – Easy to use components for slick lists
- Drag handle, auto-scrolling, locked axis, events, and more!
- Suuuper smooth animations – Chasing the 60FPS dream 🌈
- Horizontal lists, vertical lists, or a grid ↔ ↕ ⤡
- Touch support 👌
- Oh yeah, and it's DEPENDENCY FREE! 👌
Installation
Using npm:
$ npm install vue-slicksort --save
Using yarn:
$ yarn add vue-slicksort
Using a CDN:
<script src="https://unpkg.com/vue-slicksort@latest/dist/vue-slicksort.min.js"></script>
Then, using a module bundler that supports either CommonJS or ES2015 modules, such as webpack:
// Using an ES6 transpiler like Babel
import { ContainerMixin, ElementMixin } from 'vue-slicksort';
// Not using an ES6 transpiler
var slicksort = require('vue-slicksort');
var ContainerMixin = slicksort.ContainerMixin;
var ElementMixin = slicksort.ElementMixin;
If you are loading the package via <script>
tag:
<script>
var { ContainerMixin, ElementMixin, HandleDirective } = window.VueSlicksort;
</script>
Usage
Basic Example
import Vue from 'vue';
import { ContainerMixin, ElementMixin } from 'vue-slicksort';
const SortableList = {
mixins: [ContainerMixin],
template: `
<ul class="list">
<slot />
</ul>
`
};
const SortableItem = {
mixins: [ElementMixin],
props: ['item'],
template: `
<li class="list-item">{{item}}</li>
`
};
const ExampleVue = {
name: 'Example',
template: `
<div class="root">
<SortableList lockAxis="y" v-model="items">
<SortableItem v-for="(item, index) in items" :index="index" :key="index" :item="item"/>
</SortableList>
</div>
`,
components: {
SortableItem,
SortableList
},
data() {
return {
items: ['Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5', 'Item 6', 'Item 7', 'Item 8']
};
}
};
const app = new Vue({
el: '#root',
render: h => h(ExampleVue)
});
That's it! Vue Slicksort does not come with any styles by default, since it's meant to enhance your existing components.
Slicksort components
There are two pre-built components that implement the two mixins. Use them like this:
import { SlickList, SlickItem } from 'vue-slicksort';
const ExampleVue = {
name: 'Example',
template: `
<div class="root">
<SlickList lockAxis="y" v-model="items">
<SlickItem v-for="(item, index) in items" :index="index" :key="index">
{{ item }}
</SlickItem>
</SlickList>
</div>
`,
components: {
SlickItem,
SlickList
},
data() {
return {
items: ['Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5', 'Item 6', 'Item 7', 'Item 8']
};
}
};
Why should I use this?
There are already a number of great Drag & Drop libraries out there (for instance, vuedraggable is fantastic). If those libraries fit your needs, you should definitely give them a try first. However, most of those libraries rely on the HTML5 Drag & Drop API, which has some severe limitations. For instance, things rapidly become tricky if you need to support touch devices, if you need to lock dragging to an axis, or want to animate the nodes as they're being sorted. Vue Slicksort aims to provide a simple set of component mixins to fill those gaps. If you're looking for a dead-simple, mobile-friendly way to add sortable functionality to your lists, then you're in the right place.
Customization and props
You apply options as individual props
on whatever component is using the ContainerMixin
. The component also emits several events during a sorting operation. Here's an example of a customized component:
<SortableContainer :value="items"
:transitionDuration="250"
:lockAxis="'y'"
:useDragHandle="true"
@sort-start="onSortStart($event)" >
<!-- SortableElement stuff goes here -->
</SortableContainer>
ContainerMixin
Props
value
(required)
type: Array
The value
can be inherited from v-model
but has to be set to the same list that is rendered with v-for
inside the Container
axis
type: String
default: y
Items can be sorted horizontally, vertically or in a grid. Possible values: x
, y
or xy
lockAxis
type: String
If you'd like, you can lock movement to an axis while sorting. This is not something that is possible with HTML5 Drag & Drop
helperClass
type: String
You can provide a class you'd like to add to the sortable helper to add some styles to it
appendTo
type: String
default: body
You can provide a querySelector string you'd like to add to the sorting element to add parent dom
transitionDuration
type: Number
default: 300
The duration of the transition when elements shift positions. Set this to 0
if you'd like to disable transitions
draggedSettlingDuration
type: Number
default: null
Override the settling duration for the drag helper. If not set, transitionDuration
will be used.
pressDelay
type: Number
default: 0
If you'd like elements to only become sortable after being pressed for a certain time, change this property. A good sensible default value for mobile is 200
. Cannot be used in conjunction with the distance
prop.
pressThreshold
type: Number
default: 5
Number of pixels of movement to tolerate before ignoring a press event.
distance
type: Number
default: 0
If you'd like elements to only become sortable after being dragged a certain number of pixels. Cannot be used in conjunction with the pressDelay
prop.
useDragHandle
type: Boolean
default: false
If you're using the HandleDirective
, set this to true
useWindowAsScrollContainer
type: Boolean
default: false
If you want, you can set the window
as the scrolling container
hideSortableGhost
type: Boolean
default: true
Whether to auto-hide the ghost element. By default, as a convenience, Vue Slicksort List will automatically hide the element that is currently being sorted. Set this to false if you would like to apply your own styling.
lockToContainerEdges
type: Boolean
default: false
You can lock movement of the sortable element to it's parent Container
lockOffset
type: OffsetValue
or [ OffsetValue
, OffsetValue
]*
default: "50%"
When lockToContainerEdges
is set to true
, this controls the offset distance between the sortable helper and the top/bottom edges of it's parent Container
. Percentage values are relative to the height of the item currently being sorted. If you wish to specify different behaviours for locking to the top of the container vs the bottom, you may also pass in an array
(For example: ["0%", "100%"]
).
* OffsetValue
can either be a finite Number
or a String
made up of a number and a unit (px
or %
).
Examples: 10
(which is the same as "10px"
), "50%"
shouldCancelStart
type: Function
default: Function
This function is invoked before sorting begins, and can be used to programatically cancel sorting before it begins. By default, it will cancel sorting if the event target is either an input
, textarea
, select
or option
.
getHelperDimensions
type: Function
default: Function
Optional function({node, index, collection})
that should return the computed dimensions of the SortableHelper. See default implementation for more details
Events
Events are emitted from the Container element, and can be bound to using v-bind
or @
directives
@sort-start
emits: { event: MouseEvent, node: HTMLElement, index: number, collection: string }
Fired when sorting begins.
@sort-move
emits: { event }
Fired when the mouse is moved during sorting.
@sort-end
emits: { event, newIndex, oldIndex, collection }
Fired when sorting has ended.
@input
emits: Array
Fired after sorting has ended with the newly sorted list.
ElementMixin
Props
index
(required)
type: Number
This is the element's sortableIndex within it's collection. This prop is required.
collection
type: Number or String
default: 0
The collection the element is part of. This is useful if you have multiple groups of sortable elements within the same Container
. Example
disabled
type: Boolean
default: false
Whether the element should be sortable or not
HandleDirective
The v-handle
directive is used inside the draggable element.
The Container must have the :useDragHandle
prop set to true
for the handle to work as explected.
Here is an example for a simple element with a handle:
<template>
<li class="list-item">
<span v-handle class="handle"></span>
{{item.value}}
</li>
</template>
<script>
import { ElementMixin, HandleDirective } from 'vue-slicksort';
export default {
mixins: [ElementMixin],
directives: { handle: HandleDirective },
}
</script>
FAQ
Upgrade from v0.x.x
The event names have all changed from camelCase to dash-case to accommodate for inline HTML templates.
Grid support?
Need to sort items in a grid? We've got you covered! Just set the axis
prop to xy
. Grid support is currently limited to a setup where all the cells in the grid have the same width and height, though we're working hard to get variable width support in the near future.
Item disappearing when sorting / CSS issues
Upon sorting, vue-slicksort
creates a clone of the element you are sorting (the sortable-helper) and appends it to the end of the appendTo
tag. The original element will still be in-place to preserve its position in the DOM until the end of the drag (with inline-styling to make it invisible). If the sortable-helper gets messed up from a CSS standpoint, consider that maybe your selectors to the draggable item are dependent on a parent element which isn't present anymore (again, since the sortable-helper is at the end of the appendTo
prop). This can also be a z-index
issue, for example, when using vue-slicksort
within a Bootstrap modal, you'll need to increase the z-index
of the SortableHelper so it is displayed on top of the modal.
Click events being swallowed
By default, vue-slicksort
is triggered immediately on mousedown
. If you'd like to prevent this behaviour, there are a number of strategies readily available. You can use the distance
prop to set a minimum distance (in pixels) to be dragged before sorting is enabled. You can also use the pressDelay
prop to add a delay before sorting is enabled. Alternatively, you can also use the HandleDirective.
Scoped styles
If you are using scoped styles on the sortable list, you can use appendTo
prop.
Dependencies
Slicksort has no dependencies.
vue
is the only peerDependency

This library is heavily based on react-sortable-hoc by Claudéric Demers (@clauderic). A very simple and low overhead implementation of drag and drop that looks and performs great!
