This example demonstrates a React dropdown menu that lets users select a pet from a list of dog, cat, hamster, parrot, spider, or goldfish options. The selected value is managed through React's `useState` hook and displayed in the browser console via `console.log`. The `Dropdown` component uses native HTML `<select>` and `<option>` elements, with the selection state fully controlled by the parent `App` component, which passes the chosen value and a callback to update it.
