This example demonstrates a dropdown menu for selecting a pet, with a large, centered label and select element. The app uses React’s `useState` hook to track the selected value and passes it to a custom `Dropdown` component, which renders a native `<select>` element with options from a static array. Changes trigger the `onSelectedValueChange` callback, updating the displayed selection. The code relies on React 16.9 and ReactDOM, with no external data source beyond the hardcoded option list.
