JavaScript/jQuery ContextMenu - items
The items array can contain:
- Objects with fields described in this section
- Objects with any other fields. In this case, specify the itemTemplate.
If you need to update the UI component items, reassign the entire items array as shown in the following example:
contextMenuInstance.option('items', newItems);As an alternative to items, you can use the dataSource property. It accepts the DataSource object, whose underlying stores provide an API that allows you to update individual items without reassigning the entire item collection.
icon
This property accepts one of the following:
- The icon's URL
- The icon's name if the icon is from the DevExtreme icon library
- The icon's CSS class if the icon is from an external icon library (see External Icon Libraries)
- The icon in the Base64 format
- The icon in the SVG format. Ensure that the source is reliable.
