This example shows an interactive dropdown menu for selecting a pet from six options, with the current choice logged to the console. It uses React 16.9 and the `useState` hook to manage the selected value, while a reusable `Dropdown` component renders a native `<select>` element whose `onChange` event updates the state. The code imports React, ReactDOM, and the `Dropdown` component, and the UI displays a label and the dropdown with large fonts. No data source or rendering library beyond React is used.
