cytoscape-context-menus

Description

A Cytoscape.js extension to provide context menu around elements and core instance distributed under The MIT License.

Dependencies

• Cytoscape.js ^2.7.0
• 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).

require() the library as appropriate for your project:

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, context-menus, jquery ){
  context-menus( cytoscape, jquery ); // register extension
});

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

Default Options

var options = {
    // List of initial menu items
    menuItems: [/*
      {
        id: 'remove', // ID of menu item
        content: 'remove', // Display content of menu item
        tooltipText: 'remove', // Tooltip text for menu item

    ],
    // 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

};

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');
