PrimeNG's Angular component pTree TreeNode

Is there a way in Angular to retrieve the positions of nodes within a TreeNode hierarchy based on their display order?

I have data structured as TreeNode objects, which include children that can branch off further. How can I access these nodes according to their hierarchical position? For example, if child1 is a child of Children and Children is a child of 'Root', then the position of child2 would be "Root.Children.child1".

**export interface TreeNode {
label?: string;
child?: [TreeNode];
}**

Answer №1

import { TreeNode } from 'primeng/api';

Utilize the import of TreeNode without the need for an interface.

treeData: TreeNode[]=[
        {
        "label": "Documents",
        "data": "Documents Folder",
        "expandedIcon": "fa fa-folder-open",
        "collapsedIcon": "fa fa-folder",
        "children": [{  
                       "label": "Documents 2",
                       "data": "Documents Folder 2",
                       "expandedIcon": "fa fa-folder-open",
                       "collapsedIcon": "fa fa-folder",
                       "children":[{ 'same format for any number 
                                      of childrens' }]
                    }]
        }]

This p-tree structure allows for a flexible layout with unlimited child elements. You can customize the expanded and collapsed icons using icon classes from prime-ng or other font icons. Use 'expanded':true; to automatically expand a node by default.
