javascript - Bootstrap 模板 "toggle menu"按钮在 Angular 中不起作用

Question

I will use this template in an angular project. [https://startbootstrap.com/previews/simple-sidebar/][1] I have pasted all the template code in the home.component.html; As the code shows. Everything is going well, the css is loaded perfectly and is identical to how the template is in the link. What I need is for the "Toggle menu" button to work. I think it is due to the JS code found at the end of the HTML, however, I don't know how to proceed. Could you please help me. [1]: https://startbootstrap.com/previews/simple-sidebar/

对于 Angular - StackBlitz Demo

.html

// use [ngClass] to toggle the class for the div
<div class="d-flex" id="wrapper" [ngClass]="{'toggled': toggled}"></div>

// attach the click 
<button class="btn btn-primary" id="menu-toggle" (click)="onToggle()">Toggle Menu</button>

.ts

toggled = false;

onToggle(){
  this.toggled = !this.toggled;
}
