I believe I am missing something obvious as a novice but am unable to find an answer to my question.

Answer 1

You can change the button attribute to an a with the same design of a button

 <button mat-button [matMenuTriggerFor]="menu">Menu</button> <mat-menu #menu="matMenu"> <a href="http://www.google.com" mat-menu-item>Item 1</a> <button mat-menu-item>Item 2</button> </mat-menu>

Answer 2

对指向外部 URL 的按钮使用类似这样的内容：

<a mat-raised-button href="https://stackoverflow.com/">Stackoverflow</a>

Answer 3

You can use

<mat-menu #menu="matMenu">
  <button mat-menu-item  onClick="window.open('//google.com')">Item 1</button>
  <button mat-menu-item  onClick="window.open('//yahoo.com')">Item 2</button>
</mat-menu>

Using window.open will work, but if you are doing something like "mailto", you will end up with a unnecessary blank tab opening in your browser. I suggest using "location.href = " instead... so... in short... whether it's a button or a menu doesn't matter, in your HTML,

  <button mat-raised-button (click)="emailSupport()" style="width:180px;">
    Contact Support
  </button>

Then in your .ts file...

  import {Component} from '@angular/core';

@Component({
  selector: 'menu-overview-example',
  templateUrl: 'menu-overview-example.html',
  styleUrls: ['menu-overview-example.css'],
})

 export class MenuOverviewExample {
  ...
  emailSupport(){
     location.href = "mailto:email-address@gmail.com?subject='I need help'&body='write some message'";
  }
}

Answer 5

Use click event and window.open Method to navigate to external URL

<button mat-button [matMenuTriggerFor]="menu">Menu</button>
<mat-menu #menu="matMenu">
  <button mat-menu-item (click)="onClick()">Item 1</button>
  <button mat-menu-item (click)="onClick()">Item 2</button>
</mat-menu>

Component:

  import {Component} from '@angular/core';

    @Component({
      selector: 'menu-overview-example',
      templateUrl: 'menu-overview-example.html',
      styleUrls: ['menu-overview-example.css'],
    })

     export class MenuOverviewExample {
      onClick()
{
  window.open("URL");

}}

This will create a nice menu icon with your requirement,

<a style="cursor: pointer">
    <i class="material-icons" style="color:#757575" [matMenuTriggerFor]="selectMenu"
    matTooltip="Menu">more_vert</i></a>

    <mat-menu #selectMenu="matMenu">
      <button mat-menu-item>Item 1</button>
      <button mat-menu-item>Item 2</button>
    </mat-menu>
