This example shows a React-based dropdown menu for selecting a pet from a hardcoded list of six options, with the current selection displayed via a controlled component. The `Dropdown.js` file defines a reusable `<select>` element that maps over the options array, setting each option’s `selected` attribute based on the incoming `selectedValue` prop. State is managed with React’s `useState` hook in `index.js`, where `setSelectedValue` updates the selection on every change event. The UI is rendered into the DOM using `ReactDOM.render`, with styling applied via inline CSS in `index.html`. The code relies on React 16.9 and ReactDOM, but no external data source or charting library is involved.

This example demonstrates a React-based dropdown menu for selecting a pet from a list of six options. The chosen value is logged to the console and passed as a prop to a custom `Dropdown` component, which renders a native HTML `<select>` element. The component manages its state using React’s `useState` hook and updates the selection via an `onSelectedValueChange` callback. The code uses React 16.9 and ReactDOM, with the app mounted into a root div.

This example demonstrates how to build an interactive dropdown menu in React that lets users select a pet from a list of six options, with the current selection displayed in a label. The app uses React's `useState` hook to manage the selected value, and a custom `Dropdown` component renders a native HTML `<select>` element with `<option>` children. The component receives `options`, `selectedValue`, and an `onSelectedValueChange` callback, mapping over the options array to generate each choice and conditionally marking the selected one. ReactDOM renders the entire interface to the `#root` element.

This example demonstrates a pet-selection interface built with React, showing how a dropdown menu synchronizes its displayed value with application state. The user can choose from six predefined pet options, and the current selection is logged to the console. The code uses React’s `useState` hook to manage the selected value and a custom `Dropdown` component that renders a standard HTML `<select>` element. ReactDOM renders the main `App` component, which passes the options array and state update function to the dropdown via props.

This example shows a pet selector built with React, where a dropdown menu displays six pet options and the current selection is reflected in the interface. It demonstrates how React’s `useState` hook manages the selected value, while a reusable `Dropdown` component (defined with `props` for options, `id`, `selectedValue`, and `onSelectedValueChange`) renders a native `<select>` element. The code uses ReactDOM to mount the app to the `#root` element, with labels and select styled via CSS for large text.

Menus with React

A menu built with React lets a user select a pet from a dropdown list of six options. The example demonstrates a reusable `Dropdown` component that receives an array of option objects, an identifier, the currently selected value, and a callback for selection changes. The component renders a `<select>` element whose options are mapped from the data, marking the chosen value as selected. State management is handled through React's `useState` hook in the `App` component, passing the selected value to the component. The example uses React DOM for rendering, with the interface styled via the page's inline CSS.

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.

Menus with React

This example shows a React-based pet selector with a dropdown menu, where users choose from six animal options. A label and select element display the current selection, which updates in real time via React's `useState` hook. The code defines a reusable `Dropdown` component that maps over an options array to generate select elements, using `onSelectedValueChange` to handle changes and `selectedValue` to mark the active choice. The app uses `ReactDOM.render` to mount the component to the DOM, with the selected value logged to the console on each update.

This example demonstrates interactive dropdown menus built with React, allowing users to select a pet from a predefined list of six options. The selection updates a state variable and is logged to the console. The code defines a reusable `Dropdown` component that renders an HTML `<select>` element, uses React `useState` for state management, and pairs with ReactDOM to render the app. The interface uses large font styling for the label and menu, with options styled at a smaller size.
