Angular List - Item Context Menu

If you want to offer the user a set of commands related to a List item, you can do so with the context menu. To specify the commands, use the menuItems array. Each object in this array configures a single command.

const fruits = [
    { fruit: "Apples", count: 10 },
    { fruit: "Oranges", count: 12 },
    { fruit: "Lemons", count: 15 }
];

$(function() {
    $("#listContainer").dxList({
        dataSource: fruits,
        itemTemplate: function(data, _, element) {
            element.append( $("<b>").text(data.fruit) );
        },
        menuItems: [{
            text: "Add to Cart",
            action: function (e) {
                // ...
                DevExpress.ui.notify(e.itemData.fruit + " are added to cart");
            }
        }, {
            text: "View Details",
            action: function (e) {

The user can access the commands in one of the following ways depending on the value of the menuMode property.

  • "context"
    The user right-clicks or performs a long tap on an item to open the context menu with the commands.

  • "slide"
    The user swipes an item to access the commands. If the menuItems array contains a single command, swiping the item reveals the button executing this command. If there are several commands in the menuItems array, swiping the item reveals the "More" button that opens a pop-up window with these commands.
