React Contextmenu

ContextMenu in React.

Installation

npm install --save react-contextmenu

Usage

You need to setup two things:

1. The ContextMenu
2. The ContextMenuTrigger

import React from "react";
import ReactDOM from "react-dom";
import { ContextMenu, MenuItem, ContextMenuTrigger } from "react-contextmenu";

function handleClick(e, data) {
  console.log(data);
}

function MyApp() {
  return (
    <div>

      <ContextMenuTrigger id="some_unique_identifier">
        <div className="well">Right click to see the menu</div>
      </ContextMenuTrigger>

      <ContextMenu id="some_unique_identifier">
        <MenuItem data={"some_data"} onClick={this.handleClick}>
          ContextMenu Item 1
        </MenuItem>
        <MenuItem data={"some_data"} onClick={this.handleClick}>
          ContextMenu Item 2
        </MenuItem>
        <MenuItem divider />
        <MenuItem data={"some_data"} onClick={this.handleClick}>
   	      ContextMenu Item 3
        </MenuItem>
      </ContextMenu>

    </div>
  );
}

ReactDOM.render(<MyApp myProp={12}/>, document.getElementById("main"));

As you can see that the ContextMenu to be showed on any component is dependent on a unique id.

See examples for more in detail usage.

##Styling

The styling can be apllied to using following classes.

• react-contextmenu : applied to menu root element.
• react-contextmenu--visible : applied to menu root element when visible.
• react-contextmenu-item : applied to menu items.
• react-contextmenu-link : applied to menu links inside items.
