ContextMenu

ContextMenu is a context menu build on React (16.8+) hooks. ContextMenu provides a quick and easy way to create instant context menus without having to build jsx. This component supports submenus, custom component menu items, and edge detection.

Installation

Using npm:

$ npm i contextmenu

How To Use

Import:

import useContextMenu from 'contextmenu';
import 'contextmenu/ContextMenu.css';

Build out your menu:

const menuConfig = {
  'Say open': () => console.log('open'),
  'Disabled': null,
  'JSX line': <hr></hr>,
  'JSX': <div style={{height: 40, border: '1px solid green'}}>yes</div>,
  'Line': '---',
  'Submenu': {
    'Say wololol': () => console.log('wololol'),
    'Go deeper': {
      'Onceptioniningiong': () => console.log('inceptioniningiong'),
    },
    'Submenu 2': {
      'electric': console.log,
      'boogaloo': () => console.log('boogaloo'), 
    },
  },
};

Render your menu in your component:

  const [contextMenu, useCM] = useContextMenu({ submenuSymbol: 'O' });
  return <div onContextMenu={useCM(menuConfig)}>{...}{contextMenu}</div>

API

ContextMenu is built off hooks, which means you must render it within React functional components.

useContextMenu(props)

• props is optional
• props shape:

{
  submenuSymbol: jsx; // which means jsx component or string or null
  depth: number;
  // more to be added later
}

contextMenu

• Returned from useContextmenu() which contains the React.portal to be rendered (onto document.body)
• Must be in your render function, anywhere.

useCM(menuConfig)

• menuConfig is a JSON that determines what the rendered context menu looks like.
• menuConfig shape:

{
  [menu option name] :
    | [option callback]
    | [menuConfig]
    | [jsx]
    | "-----"
    | null
}

• [menu option name] is used in conjection with [option callback] to create an option that does something
• [menu option name] is used in conjection with another menuConfig to create a submenu
• [menu option name] is used with null when the item is disabled
• [jsx] shows custom renderings inside menu options ([menu option name] is unused here)
• "---" is a shortcut to display a separation line between menu items ([menu option name] is unused)
