The available options are listed bellow

data

Provides the data that are going to be displayed.

• Type: array
• Deafult: An empty array

You have to pass an array of objects of type IData:

interface IData {     code?: string,     name: string,     attributes?: IDataAttributes,     nodeExpanded?: boolean, 	nodeSelected?: boolean,     children?: IData[] } 

• code: If provided, it will be appended before the node's name followed by a dot (code.name)
• name: The node's name
• attributes: An object of type IDataAttributes ({ [key: string]: any })
• nodeExpanded: Set it to false if you want the specific node to be collapsed (hidden children)
• nodeSelected: Set it to true if you want to set this node as selected on load
• children: An array of objects of type IData

multiSelect

Set to false if you want to be able to select only one item at time

• Type: boolean
• Default: true

collapseNodes

Set to true if you want the user to be able to expand or collapse every node that has one or more children nodes

• Type: boolean
• Default: false
