I am at 48, 80
Headless component
Position persisted in sessionStorage
51, 150
useDraggable
Make elements draggable.
Usage
<script setup lang="ts">
import { ref } from 'vue'
import { useDraggable } from '.'
const el = ref<HTMLElement | null>(null)
// `style` will be a helper computed for `left: ?px; top: ?px;`
const { x, y, style } = useDraggable(el, {
initialValue: { x: 40, y: 40 },
})
</script>
<template>
<div ref="el" :style="style" style="position: fixed">
Drag me! I am at {{x}}, {{y}}
</div>
</template>
Component
<UseDraggable :initialValue="{ x: 10, y: 10 }" v-slot="{ x, y }">
Drag me! I am at {{x}}, {{y}}
</UseDraggable>
For component usage, additional props storageKey and storageType can be passed to the component and enable the persistence of the element position.
<UseDraggable storage-key="vueuse-draggable" storage-type="session">
Refresh the page and I am still in the same position!
</UseDraggable>
