To add a predefined item to the context menu, add its name and optional settings (for example, 'visible', 'text', and 'icon') to the items collection.

jQuery
JavaScript
$(function () {
    $("#file-manager").dxFileManager({
        contextMenu: {
            items: [
                // Specify a predefined item's name only
                "expandAll",
                "redo",
                // Specify a predefined item's name and optional settings
                {
                    name: "zoomIn",
                    text: "Zooming"
                }

        contextMenu: {
            items: [
                {
                    text: "Category",
                    items:[
                        {
                            text: "Item 1",
                            name: "item1"
                        },
                        {
