This example demonstrates a pet selector menu built with React, showing how a dropdown component manages state and user interaction. The interface displays a "Choose a pet" label alongside a dropdown menu containing six animal options, with a hamster preselected. The code uses React's `useState` hook to track the selected value, and ReactDOM to render the application to the page. The `Dropdown.js` component accepts options, an ID, and a selection handler, triggering state updates via the `onSelectedValueChange` callback.
