This example demonstrates a simple user interface for selecting a pet from a dropdown menu. The React application renders a labeled `<select>` element, populated with options for a dog, cat, hamster, parrot, spider, and goldfish. The selected value is managed through React's `useState` hook and logged to the console. The code uses the `Dropdown` component to handle the menu's options and change events, and leverages the React DOM library to render the application into the page's root element.
