This example shows a pet-selection dropdown menu built with React. A labeled `<select>` element displays six animal options, and choosing one updates the displayed selection state. The code defines a reusable `Dropdown` component that receives `options`, an `id`, `selectedValue`, and an `onSelectedValueChange` callback, using React’s `useState` hook to manage the selected value. ReactDOM renders the app into a `#root` div, with the dropdown styled using CSS. The implementation relies solely on React’s component and state APIs, with no external data or visualization libraries.
