Getting Started with React Tabs Component

Smart UI React targets React 18+ and current Node LTS for tooling; use TypeScript templates when you want typed props and events.

Demo source (Smart UI repo): react/source/tabs/basic/App.jsx

1 Create a Vite + React + TypeScript app

npm create vite@latest my-smart-app -- --template react-ts

```
cd my-smart-app
```
then
```
npm install
```

2 Install Smart UI for React

npm install smart-webcomponents-react

3 Import styles and render the component

Open src/App.tsx (or App.jsx if you chose JavaScript). The snippet below matches Smart UI React demos for this widget:

import 'smart-webcomponents-react/source/styles/smart.default.css';
import './App.css';
import React from "react";
import ReactDOM from 'react-dom/client';
import { Tabs, TabItem, TabItemsGroup } from 'smart-webcomponents-react/tabs';

const App = () => {
	return (
		<div>
			<Tabs selectedIndex={1}>
				<TabItem label="TAB 1">Content 1</TabItem>
				<TabItem label="TAB 2">Content 2</TabItem>
				<TabItem label="TAB 3">Content 3</TabItem>
				<TabItem label="TAB 4">Content 4</TabItem>
			</Tabs>
		</div>
	);
}

export default App;

4 Run the dev server

npm run dev

Open the URL Vite prints (often http://localhost:5173/).

Alternative: Next.js

Create an app with npx create-next-app@latest (Pages Router or App Router). Install the same package (npm install smart-webcomponents-react), then reuse the imports and default export from step 3 in pages/_app.tsx, the App Router root app/layout.tsx, or your top-level layout component so styles and the widget tree load once.

Common Use Cases

Add tab dynamically

Create new tabs at runtime

tabs.insert(tabs.length, {
  label: 'New Tab',
  content: 'Tab content here'
});

Handle tab change

Respond when user switches tabs

tabs.addEventListener('change', (e) => {
  console.log('Active tab:', e.detail.index);
});

Troubleshooting

How do I add tabs dynamically?: Use the insert method: tabs.insert(index, { label: 'Tab Label', content: 'Tab content' }).
How do I make tabs closable?: Set closeButtons = true to show close buttons on each tab.

TypeScript Support

Types ship with smart-webcomponents-react. Import the component and prop types:

import type { Tabs, TabsProps } from 'smart-webcomponents-react/tabs';

The generated wrappers expose on* callbacks (for example onChange) whose arguments are standard DOM Event values unless the widget typings narrow them further.

Live demos

Supported stacks: Smart UI targets Angular 17+, React 18+, Vue 3+, Node 18 LTS, and evergreen browsers; pin exact package versions to your org policy.
