Getting Started with React ListMenu 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/listmenu/basic/App.jsx

1 Create a Vite + React + TypeScript app

  1. npm create vite@latest my-smart-app -- --template react-ts
  2. 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 { ListMenu, MenuItem, MenuItemsGroup } from 'smart-webcomponents-react/listmenu';

const App = () => {
    // Any logic that was in init() or componentDidMount() can go here, e.g. in useEffect.
    // useEffect(() => {
    //     // componentDidMount equivalent
    // }, []);

    return (
        <div>
            <ListMenu id="listMenu" className="animation">
                <MenuItemsGroup>File
                    <MenuItem shortcut="Ctrl+N">New</MenuItem>
                    <MenuItem shortcut="Ctrl+0">Open</MenuItem>
                    <MenuItemsGroup>Open Containing Folder
                        <MenuItem>Explorer</MenuItem>
                        <MenuItem>cmd</MenuItem>
                    </MenuItemsGroup>
                    <MenuItem shortcut="Ctrl+S" disabled>Save</MenuItem>
                    <MenuItem shortcut="Ctrl+Alt+S" separator>Save As...</MenuItem>
                    <MenuItem shortcut="Alt+F4">Exit</MenuItem>
                </MenuItemsGroup>
                <MenuItemsGroup>Edit
                    <MenuItem shortcut="Ctrl+Z">Undo</MenuItem>
                    <MenuItem shortcut="Ctrl+Y" separator>Redo</MenuItem>
                    <MenuItem shortcut="Ctrl+X">Cut</MenuItem>
                    <MenuItem shortcut="Ctrl+C">Copy</MenuItem>
                    <MenuItem shortcut="Ctrl+V" disabled>Paste</MenuItem>
                </MenuItemsGroup>
                <MenuItemsGroup>Encoding
                    <MenuItem>Encode in ANSI</MenuItem>
                    <MenuItem>Encode in UTF-8</MenuItem>
                    <MenuItem>Encode in UTF-8-BOM</MenuItem>
                    <MenuItem>Encode in UTCS-2 BE BOM</MenuItem>
                    <MenuItem>Encode in UTCS-2 LE BOM</MenuItem>
                    <MenuItemsGroup separator>Character sets
                        <MenuItemsGroup>Cyrillic
                            <MenuItem>ISO 8859-5</MenuItem>
                            <MenuItem>KOI8-R</MenuItem>
                            <MenuItem>KOI8-U</MenuItem>
                            <MenuItem>Windows-1251</MenuItem>
                        </MenuItemsGroup>
                        <MenuItemsGroup>Chinese
                            <MenuItem>Big5 (Traditional)</MenuItem>
                            <MenuItem>GB2312 (Simplified)</MenuItem>
                        </MenuItemsGroup>
                        <MenuItemsGroup>Western European
                            <MenuItem>ISO 8859-1</MenuItem>
                            <MenuItem>ISO 8859-15</MenuItem>
                            <MenuItem>OEM 850</MenuItem>
                            <MenuItem>Windows-1252</MenuItem>
                        </MenuItemsGroup>
                    </MenuItemsGroup>
                    <MenuItem>Convert to ANSI</MenuItem>
                    <MenuItem>Convert to UTF-8</MenuItem>
                    <MenuItem>Convert to UTF-8-BOM</MenuItem>
                    <MenuItem>Convert to UTCS-2 BE BOM</MenuItem>
                    <MenuItem>Convert to UTCS-2 LE BOM</MenuItem>
                </MenuItemsGroup>
            </ListMenu>
        </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.

TypeScript Support

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

import type { ListMenu, ListMenuProps } from 'smart-webcomponents-react/listmenu';

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

Accessibility

The ListMenu component follows WAI-ARIA best practices:

  • Keyboard navigation - Tab, Arrow keys, Enter, and Escape are supported
  • ARIA roles - Appropriate roles and labels are applied automatically
  • Focus management - Visible focus indicators for keyboard users
  • Screen readers - State changes are announced to assistive technology
  • High contrast - Supports Windows High Contrast Mode and forced colors

For custom labeling, set aria-label or aria-labelledby attributes on the component.

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.
