Using Vue.js transitions within a loop

I am facing an issue with a transition in Vue.js where only the leave transition is working and not the enter transition. Here is my code:

<template v-for="(item, index) in imagesList">
  <transition name="fade">
    <div class="ctn">
      <div class="thumbnail">
        <img :src="item.url" :alt="item.alt" :title="item.title">
      </div>
      <div class="info">
        <p>{{ item.info }}</p>
      </div>
    </div>
  </transition>
</template>

I have used the CSS code provided in the Vue.js documentation:

.fade-enter-active, .fade-leave-active {
  transition: opacity .5s;
}
.fade-enter, .fade-leave-to {
  opacity: 0;
}

Answer №1

To ensure a smooth transition when Vue is initially rendered, make sure to include the appear attribute on the transition tag.

For a working example, visit: https://codesandbox.io/s/vue-template-rjmi9?fontsize=14&hidenavigation=1&theme=dark

If the transition does not immediately show up, try refreshing the browser in the IDE to adjust for loading speeds.

For additional information, check out: https://v2.vuejs.org/v2/guide/transitions.html#Transitions-on-Initial-Render

Consider using <transition-group> based on your requirements. Learn more here: https://v2.vuejs.org/v2/guide/transitions.html#List-Transitions
