import { Component } from '@angular/core';
import { TreeNode } from 'primeng/api';

@Component({
  selector: 'app-tree-dropdown',
  template: `
    <p-tree [value]="nodes" selectionMode="single" (onNodeSelect)="onNodeSelect($event)"></p-tree>
  `
})
export class TreeDropdownComponent {
  nodes: TreeNode[] = [
    {
      label: 'Node 1',
      data: 'Node 1 Data',
      children: [
        { label: 'Node 1.1', data: 'Node 1.1 Data' },
        { label: 'Node 1.2', data: 'Node 1.2 Data' }
      ]
    },
    {
      label: 'Node 2',
