This example demonstrates a React component that lets users select a pet from a dropdown menu, with the current choice displayed alongside the label. Using the `useState` hook, the app manages the selected value and passes it to a reusable `Dropdown` component, which renders a `<select>` element with options defined in an array. The code integrates React 16.9 and ReactDOM 16.7 with D3 v7 loaded via CDN, though no D3 visualization is used here. The interaction is handled through the `onChange` event, updating state and re-rendering the selection.

This example demonstrates a dropdown menu for selecting a pet, with the chosen value reflected in the select element’s highlighted option. It uses React’s `useState` hook to manage the selected value and a reusable `Dropdown` component that maps over an array of pet options. The component receives `options`, `onSelectedValueChange`, and `selectedValue` props, rendering a native HTML `<select>` element. The app updates the dropdown’s selection and logs the value to the console on change.

This example demonstrates a simple pet-selection interface built with React. It shows a dropdown menu that lets users choose a pet from a list of six options, including dog, cat, hamster, and parrot. The code uses React's `useState` hook to manage the currently selected value and a custom `Dropdown` component that renders an HTML `<select>` element. The `onChange` event handler updates the state whenever the user makes a selection. ReactDOM renders the `App` component into the `#root` div, with the interface styled via embedded CSS.

This example shows a pet-selection dropdown built with React. Users choose a dog, goldfish, or spider from a menu, and the selection state updates via React’s `useState` hook. The interface uses a plain `<select>` element, with options mapped from an array of objects containing `value` and `label` properties. The code relies on `ReactDOM.render` to mount the `App` component, and the dropdown’s change events are handled through an `onChange` callback that calls `setSelectedValue`. No data visualization or external charting library is present; it demonstrates basic React component composition and state management.

This example shows a simple pet-selection interface with a dropdown menu. Built using the React framework, the app renders a static list of six pet options—goldfish, dog, cat, hamster, parrot, and spider—with the hamster pre-selected. The code defines a reusable `Dropdown` component and manages its state with React's `useState` hook. The interface uses plain HTML `<select>` and `<option>` elements, styled with large fonts via CSS, and logs the chosen value to the browser console.

Fork of Menus with React

This example demonstrates a pet-selection dropdown menu built with React and D3. It shows a styled `<select>` element populated with pet options, where the currently chosen value is tracked and displayed via React state. The implementation uses React’s `useState` and the custom `Dropdown` component, embedded in a simple app rendered with `ReactDOM`. D3 version 5 and React 16.9 are loaded via CDN, while the UI is styled through CSS, highlighting the integration of React for interactivity and D3 for visualization support.

React Starter

This example demonstrates a React-controlled dropdown menu for selecting a pet, with the chosen value displayed as a label above the selection. The interface updates the selected option in real time through React’s `useState` hook, passing the current value and an update function to a reusable `Dropdown` component. The component maps over an array of pet options to generate `<option>` elements, using the `selected` attribute to highlight the active choice. The code relies on React 16.9, ReactDOM, and d3.v5, though the actual visualization is minimal—just the interactive form controls rendered as SVG-ready HTML.

Fork of Menu with Select

This example shows a React-based dropdown menu for selecting a pet from a list of six options. It combines React’s `useState` hook to manage the selected value and a reusable `Dropdown` component that renders a native HTML `<select>` element. The dropdown’s onChange handler updates the state via `onSelectedValueChange`. The code uses React 16.9 and ReactDOM for rendering, with no D3 or other visualization library involved. The styling sets a large font size for the select control and hides page overflow.

Fork of Fork of Menus with React

This example shows a single interactive dropdown menu for selecting a pet, displaying the chosen value in the console log. The interface is built with React, using the `useState` hook to manage the selection and a reusable `Dropdown` component that renders a standard `<select>` element. The code uses ReactDOM to render the app into the root HTML element, with styling from inline CSS. The pet options are hardcoded in a JavaScript array.
