This example demonstrates interactive dropdown menus built with React, allowing users to select a pet from a list of options. The interface presents a labeled select element with choices for Dog, Cat, or Gold Fish, alongside a second dropdown that renders the same options. The code uses React’s `useState` hook and `ReactDOM.render` to manage and display the UI, with components defined for `Dropdown` and `App`. The HTML file loads React 16.9 from a CDN and includes custom styling for the form elements.
