如何获取包含数据组件的ngformio的html？

import { Component, OnInit } from '@angular/core';
import { FormBuilder, FormGroup } from '@angular/forms';
import { FormioComponents } from 'ng-formio';

@Component({
  selector: 'app-my-form',
  templateUrl: './my-form.component.html',
  styleUrls: ['./my-form.component.css']
})
export class MyFormComponent implements OnInit {
  form: FormGroup;
  formModel: any;

  constructor(private formBuilder: FormBuilder) { }

  ngOnInit() {
    this.formModel = {
      components: [
        {
          type: 'textfield',
          key: 'firstName',
          label: 'First Name',
          input: true
        },
        {
          type: 'textfield',
          key: 'lastName',
          label: 'Last Name',
          input: true
        },
        // 其他数据组件...
      ]
    };

    this.form = this.formBuilder.group({});
  }
}

<form [formGroup]="form">
  <ng-formio [form]="formModel" [submission]="form.value"></ng-formio>
</form>
