vue.js - VueJS slots with v-for loop do not display proper elements -


i'm trying create component displays subset of items passed it.

so far have 'sublist' component named slots follows:

 ...  data: () => ({     startitem : 0  })  ... <template>     <div>         <slot v-for="ctr in maxitems" :name="'s-' + (ctr + startitem - 1)"></slot>     </div> </template>

in parent following:

<sublist :max-items="5">    <div v-for="(i,index) in items" :slot="'s-'+index">       {{index}}    </div> </sublist>

when loads, renders fine:

0 1 2 3 4

however when increment startitem in sublist component, output becomes:

5 1 2 3 4

so removes 0th slot , stuffs slot 5 in place. proper way replace slots or make them "dynamic"? i'm using vuejs 2.4.2

thanks @steveholgado found answer: had add :key attribute in parent v-for , wrap each slot in child in own div:

<template>     <div>         <div v-for="ctr in maxitems">             <slot :name="'s-' + (ctr + startitem - 1)"></slot>         </div>     </div> </template>
