Ways to display a specific HTML element or tag depending on the given prop in VueJs

When working with Vue.js, it's important to remember that a <template> can only have one root element. But what should be done if you need to render different html elements based on a prop?

For instance, let's say we have a <heading> component where we want to display an <h1> when the title prop is set to title, and show an <h3> if it's set to subtitle.

This leads to another question - what if we want to achieve this kind of dynamic rendering for all h tags? In other words, displaying any of these from <h1> to <h6> based on certain prop conditions.

Utilizing the is attribute empowers you to dynamically generate any HTML element (or custom component - after being imported and registered). Here is an example of how it can be used:

<template>
  <template :is="headingType">
    {{ headingContent }}
  </template>
</template>

<script>
  export default {
    props: {
      headingType: {
        type: String,
        default: 'h2' // you have the flexibility to choose from 'h1' to 'h6' here   
      },
      headingContent: {
        type: String,
        required: true
      }
    }
  }
</script>
