This example demonstrates a pet selector menu built with React, displaying a dropdown list of six pet options and reflecting the current selection through the label above it. The app uses React’s `useState` hook to manage the selected value, initializing with “hamster”, and updates the UI whenever the user changes the dropdown. It leverages the `Dropdown` component, which renders a native HTML `<select>` element, and the ReactDOM `render` method in `index.js` to mount the app to the DOM. The interface uses React 16.9 from a CDN.

This example demonstrates a simple pet-selection menu built with React, where a dropdown list lets users choose among six animals such as dog, cat, hamster, or parrot. The selected value appears in the browser console, and the interface uses large, readable text for the label and select box. The code relies on React’s `useState` hook to manage the current selection, and a custom `Dropdown` component that maps over an options array to render each `<option>` element. ReactDOM renders the app into the `#root` div, with the dropdown styled via CSS.

This example showcases a pet selector menu built with React, demonstrating how to manage state for a dropdown component. The interface displays a label and a dropdown menu containing six animal options, with the hamster preselected as the initial value. The `Dropdown.js` component is a reusable React function that renders a native HTML select element, mapping the option list and controlling the selected attribute based on the parent's state. The main `App` component uses React's `useState` hook to track the current selection, logging each change to the console, and passes the updated value back to the dropdown through a callback handler, illustrating a basic controlled-input pattern in React.

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.

This example demonstrates a simple pet-selection menu built with React, where users choose from six predefined animal options and the current selection is logged to the console. The interface uses a native HTML `<select>` element wrapped in a reusable `Dropdown` component, which receives `options`, `selectedValue`, and an `onSelectedValueChange` callback via props. The App component manages state with the `useState` hook, initializing the selection to "hamster". ReactDOM renders the component tree, while React production builds are loaded from a CDN to support the interactive behavior.

This example demonstrates a simple pet selection menu built with React. The interface presents a dropdown list of six pet options, from Dog to Goldfish, with a default selection of Hamster. The app uses React’s `useState` hook to manage the selected value and a reusable `Dropdown` component, which renders the native HTML `<select>` element. Changes to the selection are logged to the console. The component maps over an array of option objects to generate the dropdown entries, relying on React’s `ReactDOM.render` to mount the app.

This example demonstrates a pet-selection menu built with React and a reusable Dropdown component. It shows how React state manages the chosen option, displaying a label and a styled `<select>` element. The code uses React’s `useState` hook to track the selected value, initializing it to "hamster," and passes options as an array of value-label pairs to the Dropdown component. ReactDOM renders the App to the DOM, while the Dropdown’s `onChange` event updates state via a callback prop.

This example shows a pet-selection menu built with React, demonstrating how to manage form state with the `useState` hook and a reusable `Dropdown` component. The interface displays a label and a `<select>` element with five animal options, defaulting to "hamster"; changing the selection logs the chosen value to the console. The code uses React and ReactDOM from UMD builds, along with JSX syntax, to render the component tree into the `#root` element.
