Dependencies

• Cytoscape.js ^2.7.0 || ^3.0.0
• jQuery ^1.7.0 || ^2.0.0 || ^3.0.0

Usage instructions

Download the library:

• via npm: npm install cytoscape-context-menus,
• via bower: bower install cytoscape-context-menus, or
• via direct download in the repository (probably from a tag).

Import the library as appropriate for your project:

ES import:

import cytoscape from 'cytoscape';
import $ from 'jquery';
import contextMenus from 'cytoscape-context-menus';

// register extension
cytoscape.use(contextMenus, $);

// import CSS as well
import 'cytoscape-context-menus/cytoscape-context-menus.css';

CommonJS:

var cytoscape = require('cytoscape');
var jquery = require('jquery');
var contextMenus = require('cytoscape-context-menus');

contextMenus( cytoscape, jquery ); // register extension

AMD:

require(['cytoscape', 'cytoscape-context-menus', 'jquery'], function( cytoscape, contextMenus, jquery ){
  contextMenus( cytoscape, jquery ); // register extension
});

Plain HTML/JS has the extension registered for you automatically, because no require() is needed.

Default Options

    // List of initial menu items

    ],
    // css classes that menu items will have
    menuItemClasses: [
      // add class names to this list

API

var instance = cy.contextMenus( options );

An instance has a number of functions available:

instance.isActive(); // Returns whether the extension is active.

instance.appendMenuItem(item); // Appends given menu item to the menu items list.

instance.appendMenuItems(items); // Appends menu items in the given list to the menu items list.

instance.removeMenuItem(itemID); // Removes the menu item with given ID.

instance.setTrailingDivider(itemID, status); // Sets whether the menuItem with given ID will have a following divider.

instance.insertBeforeMenuItem(item, existingItemID); // Inserts given item before the existingitem.

instance.moveBeforeOtherMenuItem(itemID, existingItemID); // Moves the item with given ID before the existingitem.

instance.disableMenuItem(itemID); // Disables the menu item with given ID.

instance.enableMenuItem(itemID); // Enables the menu item with given ID.

instance.showMenuItem(itemID); // Shows the menu item with given ID.

instance.hideMenuItem(itemID); // Hides the menu item with given ID.

instance.destroy(); // Destroys the extension instance

You can also get an existing instance:

cy.contextMenus('get');
