Getting Started with Vue Accordion Component

Smart UI Vue examples target Vue 3 and Vite; enable TypeScript in create-vue when you want typed SFCs.

Demo source (Smart UI repo): vue/vue-3/src/accordion/basic/App.vue

Scaffold with Vite (Vue 3)

Run the official scaffolding tool:

npm create vue@latest

You will be prompted for TypeScript, Router, Pinia, and other options. When unsure, accept defaults and enable features later.

cd <your-project-name>
npm install
npm install smart-webcomponents
npm run dev

Vue + TypeScript

If you enabled TypeScript, use vite.config.ts with the same isCustomElement configuration as below so the compiler treats Smart UI tags as native custom elements.

Teach Vue about custom elements

Without this, Vue warns about unknown custom elements. Open vite.config.js or vite.config.ts and configure the Vue plugin so smart-* and legacy jqx-* tags are passed through to the DOM:

import { fileURLToPath, URL } from 'node:url'

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'

export default defineConfig({
  plugins: [
    vue({
      template: {
        compilerOptions: {
          isCustomElement: tag => tag.startsWith('smart-') || tag.startsWith('jqx-')
        }
      }
    })
  ],
  resolve: {
    alias: {
      '@': fileURLToPath(new URL('./src', import.meta.url))
    }
  }
})

App.vue example

Example from Smart UI Vue 3 demos for this widget:

<template>
  <div class="vue-root">
    <smart-accordion id="accordion">
      <smart-accordion-item label="First Item">First Item Content.</smart-accordion-item>
      <smart-accordion-item label="Second Item">Second Item Content.</smart-accordion-item>
      <smart-accordion-item label="Third Item">Third Item Content.</smart-accordion-item>
      <smart-accordion-item label="Fourth Item">Fourth Item Content.</smart-accordion-item>
    </smart-accordion>
  </div>
</template>

<script>
import { onMounted } from "vue";
import "smart-webcomponents/source/styles/smart.default.css";
import "smart-webcomponents/source/modules/smart.accordion.js";

export default {
  name: "app",
  setup() {
    onMounted(() => {});
  }
};
</script>

<style>
smart-accordion {
  width: 300px;
  height: 500px;
}
</style>

You can now use smart-accordion in templates; bindings and events follow Vue's normal syntax.

Run and build

Development server:

npm run dev

Then open http://localhost:5173/.

Production build:

npm run build

Output goes to ./dist.

Common Use Cases

Expand specific item
Programmatically open an accordion section
```
accordion.expand(0); // Expand first item
```
Single expansion mode
Allow only one panel open at a time
```
accordion.expandMode = 'single';
```
