useSortable

Wrapper for sortable.

For more information on what options can be passed, see Sortable.options in the Sortable documentation.

::: warning Currently, useSortable only implements drag-and-drop sorting for a single list. :::

Install

npm i sortablejs@^1

Usage

Use template ref

<script setup lang="ts">
import { useSortable } from '@vueuse/integrations/useSortable'
import { shallowRef, useTemplateRef } from 'vue'

const el = useTemplateRef('el')
const list = shallowRef([{ id: 1, name: 'a' }, { id: 2, name: 'b' }, { id: 3, name: 'c' }])

useSortable(el, list)
</script>

<template>
  <div ref="el">
    <div v-for="item in list" :key="item.id">
      {{ item.name }}
    </div>
  </div>
</template>

Use specifies the selector to operate on

<script setup lang="ts">
import { useSortable } from '@vueuse/integrations/useSortable'
import { shallowRef, useTemplateRef } from 'vue'

const el = useTemplateRef('el')
const list = shallowRef([{ id: 1, name: 'a' }, { id: 2, name: 'b' }, { id: 3, name: 'c' }])

const animation = 200

const { option } = useSortable(el, list, {
  handle: '.handle',
  // or option set
  // animation
})

// You can use the option method to set and get the option of Sortable
option('animation', animation)
// option('animation') // 200
</script>

<template>
  <div ref="el">
    <div v-for="item in list" :key="item.id">
      <span>{{ item.name }}</span>
      <span class="handle">*</span>
    </div>
  </div>
</template>

Use a selector to get the root element

<script setup lang="ts">
import { useSortable } from '@vueuse/integrations/useSortable'
import { shallowRef } from 'vue'

const list = shallowRef([{ id: 1, name: 'a' }, { id: 2, name: 'b' }, { id: 3, name: 'c' }])

useSortable('#dv', list)
</script>

<template>
  <div id="dv">
    <div v-for="item in list" :key="item.id">
      <span>{{ item.name }}</span>
    </div>
  </div>
</template>

Tips

If you want to handle the onUpdate yourself, you can pass in onUpdate parameters, and we also exposed a function to move the item position.

import { moveArrayElement, useSortable } from '@vueuse/integrations/useSortable'

useSortable(el, list, {
  onUpdate: (e) => {
    // do something
    moveArrayElement(list, e.oldIndex, e.newIndex, e)
    // nextTick required here as moveArrayElement is executed in a microtask
    // so we need to wait until the next tick until that is finished.
    nextTick(() => {
      /* do something */
    })
  }
})
