JavaScript/jQuery ContextMenu - Customize Item Appearance

For a minor customization of ContextMenu items, you can define specific fields in item data objects. For example, the following code generates three context menu items. Between the first and the second items lies a separator dividing one group of items from another. All the items are supplied with icons.

JavaScript
  • var contextMenuItems = [
  • { text: 'Zoom In', icon: 'plus' },
  • { text: 'Share', icon: 'message', beginGroup: true },
  • { text: 'Download', icon: 'download' }
  • ];
  •  
  • $(function() {
  • $("#contextMenuContainer").dxContextMenu({
  • items: contextMenuItems,
  • target: "#someElement",
  • visible: true
  • });
  • });

If you need a more flexible solution, define an itemTemplate. In Angular and Vue, you can declare it in the markup. In React, you can use a rendering function (shown in the code below) or component:

If you use jQuery, use DOM manipulation methods to combine the HTML markup for context menu items. To apply this markup, use the itemTemplate callback function as shown in the following code:

JavaScript
  • var contextMenuItems = [
  • { text: "Zoom In", icon: "plus" },
  • { text: "Share", icon: "message" },
  • { text: "Download", icon: "download" }
  • ];
  •  
  • $(function() {
  • $("#contextMenuContainer").dxContextMenu({
  • items: contextMenuItems,
  • visible: true,
  • itemTemplate: function(itemData, itemIndex, itemElement) {
  • var iconElement = $("<span></span>");
  • iconElement.addClass("dx-icon-" + itemData.icon);
  • itemElement.append(iconElement);
  • itemElement.append("<i style='margin-left:5px'>" + itemData.text + "</i>" + " [" + itemIndex + "]");
  • },
  • target: '#someElement'
  • });
  • });

You can also customize an individual context menu item. For this purpose, declare a template for this item as a script and pass its id to the template field of the item's data object.

HTML
JavaScript
  • <script id="individualTemplate" type="text/html">
  • <!-- ... -->
  • </script>
  • var contextMenuItems = [
  • { text: "Zoom In" },
  • { text: "Zoom Out" },
  • {
  • text: "Download",
  • template: $("#individualTemplate")
  • },
  • // ...
  • ];

In addition, you can use a 3rd-party template engine to customize UI component appearance. For more information, see the 3rd-Party Template Engines article.
