    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" tag="ul">
            <SlickItem v-for="(item, index) in items" :index="index" :key="index" tag="li">
              {{ 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 expected.

    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
