This example demonstrates a simple pet-selection menu built with React, displaying a dropdown list of six animal options and logging each chosen value to the console. It shows how React state manages the selected option through the `useState` hook, with the `Dropdown` component receiving options, an ID, and a change handler as props. The rendering uses ReactDOM to mount the app into the DOM, while the dropdown’s `onChange` event triggers updates to the selected value. The code includes inline HTML styling for large label and select text, and relies on React 16.9 from a CDN.
