Vue 3 Dynamic Components for Tabbed Interfaces
Implement a flexible tabbed interface in Vue 3 using dynamic components and the `is` attribute, allowing you to switch between different components dynamically based on user selection.
<!-- App.vue -->
<template>
<div class="tab-container">
<nav class="tab-nav">
<button
v-for="tab in tabs"
:key="tab.name"
:class="{ active: currentTab === tab.component }"
@click="currentTab = tab.component"
>
{{ tab.name }}
</button>
</nav>
<div class="tab-content">
<component :is="currentTab" message="Hello from Parent!"></component>
</div>
</div>
</template>
<script setup>
import { ref } from 'vue';
import HomeTab from './components/HomeTab.vue';
import ProfileTab from './components/ProfileTab.vue';
import SettingsTab from './components/SettingsTab.vue';
const currentTab = ref(HomeTab); // Initial component
const tabs = [
{ name: 'Home', component: HomeTab },
{ name: 'Profile', component: ProfileTab },
{ name: 'Settings', component: SettingsTab },
];
</script>
<style scoped>
.tab-container {
font-family: Arial, sans-serif;
max-width: 800px;
margin: 20px auto;
border: 1px solid #eee;
border-radius: 8px;
box-shadow: 0 2px 4px rgba(0,0,0,0.05);
}
.tab-nav {
display: flex;
border-bottom: 1px solid #eee;
}
.tab-nav button {
flex: 1;
padding: 15px 20px;
border: none;
background-color: #f9f9f9;
cursor: pointer;
font-size: 16px;
transition: background-color 0.3s ease;
}
.tab-nav button:hover {
background-color: #e9e9e9;
}
.tab-nav button.active {
background-color: #fff;
border-bottom: 2px solid #007bff;
color: #007bff;
}
.tab-content {
padding: 20px;
}
</style>
<!-- components/HomeTab.vue -->
<!-- <template>
<div>
<h3>Home Tab Content</h3>
<p>Welcome to the home page! {{ message }}</p>
</div>
</template>
<script setup>
import { defineProps } from 'vue';
defineProps(['message']);
</script> -->
<!-- components/ProfileTab.vue -->
<!-- <template>
<div>
<h3>Profile Tab Content</h3>
<p>Manage your profile here. {{ message }}</p>
</div>
</template>
<script setup>
import { defineProps } from 'vue';
defineProps(['message']);
</script> -->
<!-- components/SettingsTab.vue -->
<!-- <template>
<div>
<h3>Settings Tab Content</h3>
<p>Adjust your settings. {{ message }}</p>
</div>
</template>
<script setup>
import { defineProps } from 'vue';
defineProps(['message']);
</script> -->
How it works: This snippet illustrates how to create a dynamic tabbed interface using Vue 3's built-in `<component :is="...">` element. By binding `is` to a reactive variable (`currentTab`) holding a component reference, you can dynamically switch between different components without re-mounting the entire parent. Props can still be passed to the dynamic component, making this a powerful pattern for building flexible and maintainable UIs like dashboards or multi-step forms.
