How to add more fields to TreeModel interface

[gurelsoycaner]

Hı,

How can I possibly add more fields to TreeModel interface:-

export interface TreeModel {
name: string;
id: number;
code: string;
translateId: string;
options?: TreeItemOptions;
childrens: TreeModel[]; // childrens list
}

and also should show in the view, or maybe add beforeAddItemEvent that can be bind to, by so doing the developer can raise maybe a dialog modal form for data entry for the selected ITEM-ID.

please help.

Thanks in advance.
