是的，您可以通过设置每个步骤的状态来实现多个步骤的活动/显示状态。以下是一个示例：

HTML代码：

  
    

      Step 1
      
      Next
    
  
  
  
    

      Step 2
      
      Back
      Next
    
  
  
  
    Step 3
    
You are done!
    Back
  

在组件中，您可以使用以下代码设置步骤状态：

import { Component, ViewChild } from '@angular/core';
import { MatStepper } from '@angular/material/stepper';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';

@Component({
  selector: 'app-stepper',
  templateUrl: './stepper.component.html',
  styleUrls: ['./stepper.component.css']
})
export class StepperComponent {
  @ViewChild('stepper') stepper: MatStepper;
  firstFormGroup: FormGroup;
  secondFormGroup: FormGroup;

  constructor(private _formBuilder: FormBuilder) { }

  ngOnInit() {
    this.firstFormGroup = this._formBuilder.group({
      firstCtrl: ['', Validators.required]
    });
    this.secondFormGroup = this._formBuilder.group({
      secondCtrl: ['', Validators.required]
    });
  }

  // 设置每个步骤的状态
