如何在angular的JSON编辑器中添加下拉/选择框

<select [(ngModel)]="selectedOption">
  <option *ngFor="let option of options" [value]="option">{{ option }}</option>
</select>

options: string[] = ['Option 1', 'Option 2', 'Option 3'];
selectedOption: string;

npm install angular-json-editor --save

import { Component } from '@angular/core';
import { JSONEditorOptions } from 'angular-json-editor';

@Component({
  selector: 'app-json-editor',
  templateUrl: './json-editor.component.html',
  styleUrls: ['./json-editor.component.css']
})
export class JsonEditorComponent {
  editorOptions: JSONEditorOptions;

  constructor() {
    this.editorOptions = new JSONEditorOptions();
    this.editorOptions.mode = 'tree'; // 设置编辑器模式为树形结构
  }
}

<json-editor [options]="editorOptions" [(ngModel)]="jsonData"></json-editor>
