Vue TreeView Default Item Template

This section lists the data source fields that are used in a default item template.

Type:

Object

By default, a predefined item template is applied to display the items of this widget. This template is based on certain fields of the data source provided for this widget. Below is the list of these fields. If the default item template is not appropriate for your task, implement a custom item template based on these or other fields of your data source.

icon

Specifies the tree view item's icon.

Type:

String

This option accepts one of the following:

items

Holds an array of tree view items.

When specifying the items field for an item, this item becomes a root item. The child items are displayed using the same default item template as the root items. So specify the fields that take part in the default item template when defining items array objects. Alternatively, you can implement a custom item template.

NOTE
Each item of the array passed to the items option can include an items field, which takes on an object with the same structure as a root item. Therefore, you can create as many tree view levels as you need.
