Insert a blank div at a specific position within a v-for loop

Question

Insert a blank div at a specific position within a v-for loop

Within a collection page component, I am using a computed variable to pass an array of product items to a collection item component. However, I wish to insert an empty collection item after the third product is displayed. This empty collection item should act as a template without any product content inside. If anyone has suggestions on how I can achieve this functionality in Vue.js, I would greatly appreciate it.

Sample code for the collection page:

        <collection-item
          v-for="product in products" 
          :collection-item="product"
        ></collection-item>

javascript vue.js nuxt.js

One approach is to enclose your <collection-item within a template and utilize a v-for loop, adding a conditional statement with v-if to control the rendering of each collection-item

<template>
  <section>
    <template v-for="(row, index) in rows">
      <collection v-if="index !== 3" :key="index"></collection>
      <div v-else :key="index">additional content or exclusion</div>
    </template>
  </section>
</template>

In the case where you always need an empty item after the third product, one approach is to iterate over an outer container using a template instead of individual collection-item components. By utilizing a combination of v-if and the index property provided by v-for, you can achieve this desired layout.

<template v-for="(product, index) in products">
    <collection-item :collection-item="product" />
    <collection-item v-if="index == 2" />
</template>

Alternatively, you could programmatically insert an empty product at the third position within your array. This method achieves the same result but may not be as visually clear as incorporating it directly in the template structure.

Furthermore, when implementing v-for on custom components, it is crucial (especially since Vue v2.2.0) to include a key property for distinguishing between rendered list elements. Ideally, this key should be a unique identifier for each element, such as product.id. As a fallback, utilizing the index can suffice if no conflicts arise with this approach.
