Generate several different elements

Is it possible to use Vue.js to render a component multiple times based on a variable?

For instance, I have a size variable set to 5 and I want to display the Widget component 5 times.

Here is my current code snippet:

Template :

<template>
    <div v-for="item in size" :key="item">
        <Widget/>
    </div>
</template>

Script :

import Widget from './Widget'
export default {
    data () {
        return {
            size: 5
        }
    },
    components: {
        Widget
    }
}

I've tried using v-for but I'm having trouble understanding its functionality.

Answer №1

If a component has only one root element, using v-for on the outermost element will result in an error because it would generate multiple root elements. You can resolve this issue by implementing either of these solutions:

<template>
    <div>
        <div v-for="item in size" :key="item">
            <Widget/>
        </div>
    </div>
</template>

OR

<template>
    <div>
        <Widget v-for="item in size" :key="item" />
    </div>
</template>

Answer №2

To achieve a specific quantity of widgets, you can use the following code snippet:

<Widget v-for="item in 5" :key="item" />

It is important to note that using v-for directly on the root template element of a component is not supported.
