The TreeView works with object collections that can have a plain or hierarchical structure. Depending on the structure, the objects should provide different data fields. Specify the dataStructure property to notify the TreeView of the used structure and refer to the property's description for information on the required fields.
If you need to update the UI component items, reassign the entire items array as shown in the following example:
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.
The TreeView component evaluates the html property's value. This evaluation, however, makes the TreeView 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.
This property accepts one of the following:
The following types of the specified value are available.
- Assign a string containing the name of the required template.
- Assign a jQuery object of the template's container.
- Assign a DOM Node of the template's container.
- Assign a function that returns the jQuery object or a DOM Node of the template's container.
