This example demonstrates a simple pet-selection dropdown menu built with React. It shows how React state manages the currently selected option, with a custom `Dropdown` component that renders a `<select>` element and updates the selection via an `onSelectedValueChange` callback. The code uses React’s `useState` hook, `ReactDOM.render`, and JSX to bind the dropdown’s options from a hardcoded array. The current value is logged to the console on each change, but no further data visualization or external data source is included.
