JavaScript/jQuery DropDownButton - items

Provides drop-down menu items.

Default Value: null

The items array can contain:

If you need to update the UI component items, reassign the entire items array as shown in the following example:

JavaScript
dropDownButtonInstance.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.

NOTE
Do not use the items property if you use dataSource, and vice versa.

badge

Specifies the text of a badge displayed for the list item.

Type:

String

If the property value is undefined or an empty string, the badge is not displayed.

disabled

Specifies whether the UI component item responds to user interaction.

Type:

Boolean

Default Value: false

html

Specifies the HTML markup to be inserted into the item element.

Type:

String

The DropDownButton component evaluates the html property's value. This evaluation, however, makes the DropDownButton potentially vulnerable to XSS attacks. To guard against these attacks, encode the HTML markup before you assign it to the html property. Refer to the following help topic for more information: Potentially Vulnerable API - html.

You can use the text property as a safe alternative.

icon

Specifies the list item's icon.

Type:

String

This property accepts one of the following:

onClick

A handler for the click event raised for a certain item in the drop-down field.

Type:

Function

Function parameters:

The following types of the specified value are available.
