A React-based menu interface displays a dropdown for selecting a pet from a fixed list of options (goldfish, dog, cat, hamster, parrot, spider, and b). The component uses React’s `useState` hook to manage the currently selected value and logs each selection to the console. The `Dropdown` component is created as a reusable function that renders a native HTML `<select>` element, mapping options to `<option>` tags and triggering a callback on change. ReactDOM renders the app into the `#root` div, with styling applied via embedded CSS that enlarges labels and selects.
