This example shows a React class-based application with a dropdown menu for selecting a pet. The dropdown updates a displayed selection using React's component state, managed through a constructor and the `handleChange` method, rather than hooks. The `Dropdown` component receives options, a selected value, and an onChange callback, rendering a native `<select>` element with styled labels. The code uses React 16.13.1, ReactDOM 17.0.1, and D3 v6.2.0, though D3 is loaded but not visibly used in the interaction logic.

Dropdown Menu

This example demonstrates a dropdown menu for selecting a pet, with the chosen value displayed in the browser’s console. The interface is built using React hooks (`useState`) to manage the selected option and a custom `Dropdown` component that renders a native `<select>` element. Styling is applied via CSS, while the page loads React, ReactDOM, and D3 v5 from CDNs, though D3 itself is not used in the visible logic. The rendering is SVG-based, as indicated by commented-out circles in the HTML markup.

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.

React Dropdown Menus

This example demonstrates a simple React dropdown menu for selecting a pet, with a large, readable interface optimized for demonstration purposes. The code uses React 16.9.0 and ReactDOM to render a single `<select>` element containing seven options, including a placeholder prompt. Styling is applied via inline CSS in the HTML file, adjusting font sizes for the label and select controls. The application mounts to a root `<div>` element, and the implementation is minimal, showing basic form control composition without any external data sources or event handling logic.

Drop Down

This example demonstrates a pet selector interface built with React and D3. It shows a dropdown menu populated with five pet options, defaulting to "Dog," and logs the selected value to the console. The implementation uses React's `useState` hook to manage the selected value and a custom `DropDown` component that renders an HTML `<select>` element. The component accepts `options`, `selectedValue`, and an `onSelectedValueChange` callback, triggering the state update on user interaction. The code relies on React 16.9 and ReactDOM for rendering.

menu react

This example shows a pet selector dropdown built with React, where choosing a pet from the menu updates the selected value state. The interface renders a labeled `<select>` element using a reusable `Dropdown` component that maps over six predefined pet options. The code uses React’s `useState` hook to manage the current selection and ReactDOM to render the app into the DOM, while D3 is loaded only for potential charting, though no visualization is drawn here.

Dropdown menu with react and d3

This example demonstrates a pet-selector dropdown menu that displays a list of six animal options and updates a selected value in real time as the user makes a choice. The visualization is built using React's `useState` hook to manage the selected value and a custom `Dropdown` component that renders an HTML `<select>` element. The code imports React and ReactDOM, and the dropdown’s options are defined in an array of objects with `value` and `label` properties. No D3 library is used; the example relies purely on React’s component model and event handling via `onChange`.

dropdown menu 1

This example shows a React-based dropdown menu for selecting a pet from a list of six options, with the chosen value displayed via a console log. It demonstrates controlled component state using React’s `useState` hook, passing the selected value and an update function to a reusable `Dropdown` component. The component renders a native HTML `<select>` element, mapping over an array of option objects with `value` and `label` properties, and marks the current selection with the `selected` attribute. The app is mounted with `ReactDOM.render` into a root div, styled with large fonts in the HTML.
