This example shows a chocolate selector interface built with React, displaying a dropdown menu with six chocolate brands and updating a selected value label. The app uses the React `useState` hook to manage the currently chosen option, passing it as a prop to a reusable `Dropdown` component. ReactDOM renders the component tree into the root div, while a label and `<select>` element provide the interactive UI. The options are hardcoded in an array, and the initial selection is set to "cadbuary". The code relies on React 16.9 and vanilla JavaScript, with no external data sources or visualization libraries.
