Demo

Here are demos: simple and customized, respectively:

Dependencies

• Cytoscape.js ^2.7.0 || ^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:

Note: es import doesn't work for plain javascript applications because webpack doesn't support es module output at the moment.

import cytoscape from 'cytoscape';
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 contextMenus = require('cytoscape-context-menus');

contextMenus(cytoscape); // register extension

AMD:

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

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

Default Options

var options = {
    // Customize event to bring up the context menu
    // Possible options https://js.cytoscape.org/#events/user-input-device-events
    evtType: 'cxttap',
    // List of initial menu items
    // A menu item must have either onClickFunction or submenu or both
    menuItems: [/*
      {
        id: 'remove', // ID of menu item
        content: 'remove', // Display content of menu item
        tooltipText: 'remove', // Tooltip text for menu item
        image: {src : "remove.svg", width : 12, height : 12, x : 6, y : 4}, // menu icon
        // Filters the elements to have this menu item on cxttap
        // If the selector is not truthy no elements will have this menu item on cxttap
        selector: 'node, edge', 
        onClickFunction: function () { // The function to be executed on click
          console.log('remove element');
        },
        disabled: false, // Whether the item will be created as disabled
        show: false, // Whether the item will be shown or not
        hasTrailingDivider: true, // Whether the item will have a trailing divider
        coreAsWell: false // Whether core instance have this item on cxttap
        submenu: [] // Shows the listed menuItems as a submenu for this item. An item must have either submenu or onClickFunction or both.
      },
      {
        id: 'hide',
        content: 'hide',
        tooltipText: 'hide',
        selector: 'node, edge',
        onClickFunction: function () {
          console.log('hide element');
        },
        disabled: true
      },
      {
        id: 'add-node',
        content: 'add node',
        tooltipText: 'add node',
        image: {src : "add.svg", width : 12, height : 12, x : 6, y : 4},
        selector: 'node',
        coreAsWell: true,
        onClickFunction: function () {
          console.log('add node');
        }
      }*/
    ],
    // css classes that menu items will have
    menuItemClasses: [
      // add class names to this list
    ],
    // css classes that context menu will have
    contextMenuClasses: [
      // add class names to this list
    ],
    // Indicates that the menu item has a submenu. If not provided default one will be used
    submenuIndicator: { src: 'assets/submenu-indicator-default.svg', width: 12, height: 12 }
};

Note: selector and coreAsWell options are ignored for the items that are inside a submenu. Their visiblity depends on their root parent's visibility.

API

Instance API

var instance = cy.contextMenus(options);

instance.isActive()

• Returns whether the extension is active.

instance.appendMenuItem(item, parentID = undefined)

• Appends given menu item to the menu items list.
• If parentID is specified, the item is inserted to the submenu of the item with parentID.
• If the parent has no submenu then it will automatically be created.
• If not specified item will be inserted to the root of the contextmenu

instance.appendMenuItems(items, parentID = undefined)

• Same with above but takes an array of items

instance.removeMenuItem(itemID)

• Removes the menu item with given ID and its submenu along with

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.moveToSubmenu(itemID, options = null)

• Moves the item with given ID to the submenu of the parent with the given ID or to root with the specified options
• If options is a string, then it is the id of the parent
• If options is a { selector?: string, coreAsWell?: boolean }, then old properties are overwritten by them and the menu item is moved to the root. If it doesn't have either properties item is not moved.
• If options is null or not provided, then it is just moved to the root

instance.moveBeforeOtherMenuItem(itemID, existingItemID)

• Inserts the item before the existingItem and moves it to the submenu that contains 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

instance.swapItems(x, y)

• Changes the order of items. x and y are id of context menu items to be swapped

instance.getOptions()

• Returns the used options

Other API

cy.contextMenus('get')

• Returns the existing instance to the extension

Build targets

• npm run build : Build ./src/** into cytoscape-edge-editing.js in production environment and minimize the file.
• npm run build:dev : Build ./src/** into cytoscape-edge-editing.js in development environment without minimizing the file.

Publishing instructions
