What is the reason for the "v-if" directive failing to display the hidden element after data has been updated?

Currently, I am utilizing Vue 2. Upon the initial rendering, the element is hidden; however, upon clicking on .mobile-trigger, Vue-DevTools indicate that the variable "mobileMenuIsOpen" changes to true. Nevertheless, the .overlay element does not yet exist in the DOM.

.mobile-trigger(@click='mobileMenuIsOpen = true')

.overlay(v-if='mobileMenuIsOpen')

...

data () {
  return {
    mobileMenuIsOpen: false
  }
}

Answer №1

Shoutout to all those who took the time to read this and share their thoughts on this post. I neglected to mention that I am utilizing the Pug (Jade) preprocessor in the code provided. Unfortunately, I did not include enough code for you to assist me.

The issue stemmed from placing the "v-once" directive within the root element of the component.
