React-contexify

A declarative context menu for React !

⚠️ The v3 introduces a lot of breaking changes. Please consider reading the migration guide.

Installation

or
$ npm install --save react-contexify

Usage

The gist

import { ContextMenu, Item, Separator, Submenu, ContextMenuProvider } from 'react-contexify';
import 'react-contexify/dist/ReactContexify.min.css';

const onClick = ({ event, ref, data, dataFromProvider }) => console.log('Hello');
// create your menu first
const MyAwesomeMenu = () => (
    <ContextMenu id='menu_id'>
       <Item onClick={onClick}>Lorem</Item>
       <Item onClick={onClick}>Ipsum</Item>
       <Separator />
       <Item disabled>Dolor</Item>
       <Separator />
       <Submenu label="Foobar">
        <Item onClick={onClick}>Foo</Item>
        <Item onClick={onClick}>Bar</Item>
       </Submenu>
    </ContextMenu>
);

const App = () => (
    <div>
        <h1>Welcome to My App</h1>
        <ContextMenuProvider id="menu_id">
            <div>Some Content ... </div>
        </ContextMenuProvider>
        <MyAwesomeMenu />
    </div>
);

Wrap component with the Component of your choice

The ContextMenuProvider expose a component prop to let you do render a custom component or any valid html tag.

Html tag

If you just want to replace the default html tag, just pass the desired tag to component:

const ComponentWithMenu = (props) => (
  <ContextMenuProvider id="menu_id" component="li">
    <h4>{props.cel1}</h4>
    <h4>{props.cel2}</h4>
  </ContextMenuProvider>
);

Custom Component

If you want to use a custom component, it works like react-router. Don't forget to render the chilren and
to grab the event to trigger the context menu:

const CustomComponent = ({ children, ...rest  }) => (
 <aside {...rest}>
    <div>
        {children}
    </div>
 </aside>
);

const ComponentWithMenu = (props) => (
  <ContextMenuProvider id="menu_id" component={CustomComponent}>
    <h4>{props.cel1}</h4>
    <h4>{props.cel2}</h4>
  </ContextMenuProvider>
);

Using a render props

You can also use a render props:

const ComponentWithMenu = (props) => (
  <ContextMenuProvider id="menu_id" render={({ children, ...rest  }) => ( 
      <aside {...rest}>
        <div>
            {children}
        </div>
    </aside>)}
    >
    <h4>{props.cel1}</h4>
    <h4>{props.cel2}</h4>
  </ContextMenuProvider>
);

Disable an Item

You can disable an Item with a boolean or a callback. When a callback is used, a boolean must be returned. The callback has access to the same parameter as the onClick callback.

const isDisabled = ({ event, ref, data, dataFromProvider }) => {
    return true;
}

<ContextMenu id='menu_id'>
    <Item disabled>Foo</Item>
    <Item disabled={isDisabled}>Bar</Item>
</ContextMenu>

Disable a submenu

Disable a Submenu is simple as disabling an Item. The disabled callback is slightly different, there is no data param.

<ContextMenu id='menu_id'>
    <Item>Foo</Item>
    <Submenu label="Submenu" disabled>
        <Item>Bar</Item>
    </Submenu>
</ContextMenu>

Change the Submenu arrow

<ContextMenu id='menu_id'>
    <Item>Foo</Item>
    <Submenu label="Submenu" arrow="?">
        <Item>Bar</Item>
    </Submenu>
    <Separator />
    <Submenu label="Submenu" arrow={<i className="rocket">?</i>}>
        <Item>Bar</Item>
    </Submenu>
</ContextMenu>

The onClick callback

The onClick callback of the Item component gives you access to an object with 4 properties:

event

The event property refers to the native event which triggered the menu. It can be used to access the mouse coordinate or any other event prop.

const onClick = ({ event, ref, data, dataFromProvider }) => {
    // Accessing the mouse coordinate
    console.log(event.clientX, event.clientY);
}

ref

If you wrap a single react component ref will be the mounted instance of the wrapped component.

If you wrap more than one component ref will be an array containing a ref of every component.

ref will be an instance of the react component only if the component is declared as a class

For more details about ref please read this

With a single component

const Wrapped = () => (
    <ContextMenuProvider id="id">
        <Avatar id="foobar" />
    </ContextMenuProdider>
);

const onClick = ({ event, ref, data, dataFromProvider }) => {
   // Retrieve the Avatar id
   console.log(ref.props.id); 
}

With more than one component

const Wrapped = () => (
    <ContextMenuProvider id="id">
        <Avatar id="foobar" />
        <Avatar id="plop" />
    </ContextMenuProdider>
);

const onClick = ({ event, ref, data, dataFromProvider }) => {
   // Print foobar
   console.log(ref[0].props.id); 

   // Print plop
   console.log(ref[1].props.id); 
}

With an html node, the ref contains the html node ?

const Wrapped = () => (
    <ContextMenuProvider id="id">
        <div id="foobar" data-xxx="plop">bar</div>
    </ContextMenuProdider>
);

const onClick = ({ event, ref, data, dataFromProvider }) => {
   // Retrieve the div id
   console.log(ref.id); 

   // Access the data attribue
   console.log(ref.dataset.xxx); 
}

With more than one html node wrapped you get an array as well.

data

const onClick = ({ event, ref, data, dataFromProvider }) => {
   // Print Ada
   console.log(data.name); 
}

const YourMenu = () => (
    <ContextMenu>
        <Item data={name: 'Ada'} onClick={onClick}>Hello</Item>
    </ContextMenu>
);

dataFromProvider

The data prop passed to the ContextMenuProvider is accessible for every Item as dataFromProvider.

const Wrapped = () => (
    <ContextMenuProvider id="id" data={name: 'Ada'}>
        <div id="foobar" data-xxx="plop">bar</div>
    </ContextMenuProdider>
);

const onClick = ({ event, ref, data, dataFromProvider }) => {
   // Print Ada Again 
   console.log(dataFromProvider.name); 
}

Why use destructuring assignment?

As a developer, pick only what you want: ({ ref }) => {}
As a maintainer, easier to extend the library: ({ event, ref, data, dataFromProvider, theFithParameter }) => {}
'destructuring'.substring(-1, 8) ?

Api

// You can set built-in theme and animation using the provided helpers as follow
import { ContextMenu, Item, theme, animation } from 'react-contexify';

<ContextMenu id="foo" theme={theme.dark} animation={animation.pop}>
    <Item>Foo</Item>
    <Item disabled>Bar</Item>
    {/* and so on  */}
</ContextMenu>

Submenu

Don't expect any props. It's just a separator xD.

<Separator />

To-Do

[ ] Allow keyboard navigation
[ ] Switch or not to styled component?
[ ] Accessibility
[ ] RTL support

Migration from v2 to v3

A huge part of the code has been reviewed. The api has been simplified.

There is no more leftIcon and rightIcon on the Item component. Do <Item><IconFont className="fa fa-delete" /> delete</Item> instead
The menuProvider HOC has been removed. You can create yours easely
The onClick callback use destructuring assignment over explicit parameter
renderTag as been replaced by component and render props. Same api as react-router
