Contextmenu

Jspreadsheet enables customization of the context menu by defining a method with the contextmenu property. The handler receives default items, section info, coordinates, and extra information, allowing developers to create new entries based on conditions and rules within the application.

Customize the menu via plugins
Plugins is a convenient way to customize the contextmenu of your application. Learn more.

Documentation

The event handler

/**
 * Customize the items of the (JavaScript data grid) context menu.
 * @param {object} worksheet - Instance of the active worksheet
 * @param {number} x - column number
 * @param {number} y - row number
 * @param {object} event - mouse event handler
 * @param {items[]} items - default contextmenu items
 * @param {string} section - Available: nested | header | row | cell | selectall | tabs | cloning | toolbar | footer
 * @param {mixed} a1 - this is a first mixed argument that depends on the section
 * @param {mixed} a2 - this is a second mixed argument that depends on the section
 */
contextMenu(worksheet: Object, x: Number, y: Number, e: Object, items: [], section: String, a1: Any, a2: Any) => []


Properties for each entry

As previously mentioned, the contextmenu custom handler should return an array of menu items. Each item in the array is an object that can have the following properties.
Property Description
type: string Context menu item type: line | divisor | default
title: string Contextmenu item title
icon: string Context menu icon key. (Material icon key icon identification)
id: string HTML id property of the DOM element
disabled: boolean The item is disabled
onclick: function Specific onclick event for the element.
shortcut: string A short description or instruction for the item. Normally a shortcut.
tooltip: string Show this text when the user mouse over the element
submenu: Array of items Submenu items

How to translate the data grid contextmenu options? You can use jSuites.setDictionary to define the word in english and the desirable translation.
