Menus with React

This example shows a pet-selection interface built with React, where users choose from a dropdown menu of goldfish, dog, or cat. It demonstrates state management with React’s `useState` hook, rendering a `<select>` element and dynamically highlighting the selected option. The app uses ReactDOM to render the component tree, with the dropdown options defined as an array of value-label pairs. The selected value is logged to the console, and the interface updates live as the user changes the selection.

This example shows an interactive dropdown menu for selecting a pet, with the chosen option displayed in a label. The interface is built with React’s `useState` hook to manage the selected value, while a custom `Dropdown` component renders the `<select>` element and its options. D3 is loaded but not directly used in the interaction logic, serving only as a dependency in the page setup. The code imports React and ReactDOM, maps over an array of pet options, and updates the selection state via the `onSelectedValueChange` callback.

This example demonstrates a React-based dropdown menu for selecting a pet, with the chosen value logged to the console and reflected in the selected option. It uses the `useState` hook to manage the selected value and a reusable `Dropdown` component that renders a `<select>` element. The code integrates React 17 and D3 v7 via CDN, with a custom `onSelectedValueChange` callback to update state. The interface includes a labeled dropdown with options for dog, cat, hamster, parrot, spider, and goldfish, styled with large text for readability.

This example shows how to create an interactive menu in React using controlled components. The app renders a dropdown of pet options, and the selected value is managed by React’s `useState` hook, logging each choice to the console. The reusable `Dropdown` component receives `options`, `id`, `selectedValue`, and an `onSelectedValueChange` callback, using the native HTML `select` element. The code relies on React 18 and ReactDOM for rendering, while D3 v7 is loaded but not explicitly used in the visible logic.

Menus with react

This example demonstrates a pet-selection menu built with React and D3. The interface displays a dropdown list of animal options, and selecting a pet updates the displayed value through React state. The `DropDown` component renders a `<select>` element, mapping over the options array and using the `selectedValue` prop to mark the chosen item. React’s `useState` hook manages the selection, while D3’s utility functions support the overall rendering pipeline, though the menu itself relies on native HTML form controls.

This example demonstrates interactive dropdown menus built with React, showing a pet selection interface where users choose from options like goldfish, spider, and hamster. The React component `Dropdown` manages the menu, while `useState` tracks the selected value and updates it through an `onSelectedValueChange` callback. The code uses React 16.9.0 and ReactDOM to render the interface, with options defined in a static array in `index.js`. The example highlights how React handles form state and event-driven UI updates in a visualization context.

A React-based menu interface displays a dropdown for selecting a pet from a fixed list of options (goldfish, dog, cat, hamster, parrot, spider, and b). The component uses React’s `useState` hook to manage the currently selected value and logs each selection to the console. The `Dropdown` component is created as a reusable function that renders a native HTML `<select>` element, mapping options to `<option>` tags and triggering a callback on change. ReactDOM renders the app into the `#root` div, with styling applied via embedded CSS that enlarges labels and selects.

This example shows a pet-selection menu built as a React component, demonstrating how to manage and update a dropdown’s state. The `Dropdown` component renders a native `<select>` element, mapping an array of pet options into `<option>` tags. The main `App` component uses React’s `useState` hook to track the selected value, initially set to “goldfish,” and passes both the current value and an `onSelectedValueChange` callback to update it on user interaction. The UI is styled with large labels and select text, and the example runs in a browser using ReactDOM to mount the app.
