<template>
<div>
<virtualList :size="40" :remain="8">
<Item v-for="(item, index) of items" :item="item" :key="item.id" />
</virtualList>
</div>
</template>
<script>
import Item from '../item.vue'
import virtualList from 'vue-virtual-scroll-list'
export default {
name: 'demo',
data () {
return {
items: [...]
}
},
components: { Item, virtualList }
}
</script>The <Item> component is included inside but defined outside the <virtualList> component. We see that <virtualList> not rely on <Item> component. So you can use virtual-list with any list item component freely.
