Contextmenu

There are two possible ways to customize the context menu: defining a custom handler using the initial menu property or via a custom plugin. The handler will intercept, change the default items or cancel the user action. This method receives the default items, the section, and some other extra information about the click, such as coordinates.

The event handler

EventDescription
contextmenu contextmenu(worksheet: Object, col: Number, row: Number, event: Object, items: Array, section: String, a1: Any, a2: Any) => Array
@param {object} worksheet - Instance of the active worksheet
@param {number=} col - column number
@param {number=} row - row number
@param {object} event - mouse event handler
@param {array} items - default contextmenu items
@param {string} section - section clicked. Sections: 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


Item properties

As previously stated, the contextmenu custom handler should return an array of items. Each item is an Object and the following properties can be used
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


Translation

You can add the following code to translate the context menu. See a working example here.

jspreadsheet.setDictionary({
    'Rename this worksheet': 'Renomear worksheet',
    'Delete this worksheet': 'Apagar worksheet',
    'Are you sure?': 'Tem certeza?',
    'Rename this cell': 'Renomear essa celula',
    'Cut': 'Cortar',
    'Copy': 'Copy',
    'Paste': 'Colar',
    'Insert a new column before': 'Inserir uma coluna antes',
    'Insert a new column after': 'Inserior uma coluna depois',
    'Insert a new column after': 'Inserior uma coluna depois',
    'Delete selected columns': 'Apagar colunas selecionadas',
    'Rename this column': 'Renomar essa coluna',
    'Create a new row': 'Criar uma nova linha',
    'Order ascending': 'Ordenar asc',
    'Order descending': 'Ordenar desc',
    'Insert a new row before': 'Inserir uma linha antes',
    'Insert a new row after': 'Inserir uma nova linha depois',
    'Delete selected rows': 'Apagar linhas selecionadas',
    'Edit notes': 'Editar notas',
    'Add notes': 'Adicionar notas',
    'Notes': 'Notas',
    'Clear notes': 'Apagar notas',
    'Save as': 'Salvar como',
    'About': 'Sobre',
});

Jspreadsheet uses jSuites contextmenu plugin. For more details and example, please visit: https://jsuites.net/v5/contextmenu.



Examples

Customize the contextmenu with a few basic options depending on the section clicked.
