This example demonstrates a dropdown menu for selecting a pet, with the chosen value displayed immediately. Built with React 16.9, it uses the `useState` hook to manage the selected value and a custom `Dropdown` component that renders a native `<select>` element, mapping over an array of pet options to create `<option>` tags. The menu updates via the `onSelectedValueChange` callback, which sets the new state and logs it to the console. The interface is styled with large fonts for visibility.
