Menus with React

This example demonstrates interactive dropdown menus built with React, showing a pet selection interface where users choose from options like goldfish, spider, and hamster. The React component `Dropdown` manages the menu, while `useState` tracks the selected value and updates it through an `onSelectedValueChange` callback. The code uses React 16.9.0 and ReactDOM to render the interface, with options defined in a static array in `index.js`. The example highlights how React handles form state and event-driven UI updates in a visualization context.

This example demonstrates a pet-selection menu built entirely with React, showing how dropdown state updates the displayed choice. It renders a labeled `<select>` element with five hard-coded options (goldfish, cat, hamster, spider, parrot) and initializes the selection to "hamster." The `Dropdown` component receives `options`, `selectedValue`, and an `onSelectedValueChange` callback, leveraging React’s `useState` hook to manage the selected value and update the UI on each change. The code uses React 16.9 and ReactDOM to mount the app, with custom styling applied via inline CSS.

This example shows a pet-selection menu built as a React component, demonstrating how to manage and update a dropdown’s state. The `Dropdown` component renders a native `<select>` element, mapping an array of pet options into `<option>` tags. The main `App` component uses React’s `useState` hook to track the selected value, initially set to “goldfish,” and passes both the current value and an `onSelectedValueChange` callback to update it on user interaction. The UI is styled with large labels and select text, and the example runs in a browser using ReactDOM to mount the app.

This example demonstrates a React dropdown menu that lets users select a pet from a list of dog, cat, hamster, parrot, spider, or goldfish options. The selected value is managed through React's `useState` hook and displayed in the browser console via `console.log`. The `Dropdown` component uses native HTML `<select>` and `<option>` elements, with the selection state fully controlled by the parent `App` component, which passes the chosen value and a callback to update it.

This example demonstrates interactive dropdown menus built with React. The application displays a "Choose a pet" label alongside a select element populated with a list of pet options, including Dog, Cat, Hamster, Parrot, Spider, and Goldfish. The interface uses React's `useState` hook to manage the selected value, with the `Dropdown` component receiving options and a callback to update the state. ReactDOM renders the application to the root element, while the HTML page loads React and ReactDOM from unpkg CDN and uses a custom `bundle.js` for the compiled code.

This example demonstrates a pet-selection interface built with React, showing how dropdown menus manage state and re-render dynamically. It uses React hooks (`useState`) to track the selected value, initialized to "hamster," and passes it through a custom `Dropdown` component defined in `Dropdown.js`. The component maps over an array of pet options (goldfish, dog, cat, etc.) to generate `<option>` elements, triggering updates via the `onSelectedValueChange` callback. The page is styled with large typography and rendered into the DOM using `ReactDOM.render`.

This example shows a simple pet selector interface built with React. A dropdown menu lets a user choose from a list of animals—dog, cat, hamster, parrot, spider, and goldfish—with the currently selected value displayed via a console log. The implementation uses React's `useState` hook to track the selected value and a custom `Dropdown` component that renders an HTML `<select>` element, mapping options with `options.map`. The app is mounted into the DOM using `ReactDOM.render` from the ReactDOM library, with the UI styled through inline CSS in the index.html file.

This example demonstrates how to build interactive dropdown menus using React, showing a pet selection interface that updates its state as the user chooses an option. The code uses React’s `useState` hook to manage the selected value and a custom `Dropdown` component that renders a native HTML `<select>` element. It leverages ReactDOM’s `render` method to mount the app, with options defined as a static array of pet objects. The example highlights React’s component-based approach for handling user input and state management without external visualization libraries.
