What are transition groups in Vue 3?

Transition groups in Vue 3 are used to apply transition effects to a list of items when they enter or leave the DOM.

How do I implement a transition group in my Vue 3 application?

You can implement a transition group by using the <transition-group> component and specifying the name and tag attributes.

Can you show me a code example?

Sure! Here's a simple example:

<template>
  <transition-group name="fade" tag="div">
    <div v-for="item in items" :key="item.id">{{ item.text }}</div>
  </transition-group>
</template>

What CSS styles should I use for the fade effect?

You can use the following CSS:

.fade-enter-active, .fade-leave-active {
  transition: opacity 0.5s;
}
.fade-enter, .fade-leave-to {
  opacity: 0;
}
