Answer 1

I am very new to Angular and tried to create vertical tabs using tabs, Sidenav and mat-action-list. I had to create separate component for tabs with hidden headers (because of ViewEncapsulation.None usage)

I don't know how to create stackblitz content yet. Here is very basic implementation. Hope it helps someone.

app.component.html

     <mat-sidenav-container class="side-nav-container">
      <mat-sidenav mode="side" opened class="sidenav">
          <mat-action-list>
              <button mat-list-item (click)="index = 0"> tab 1 </button>
              <button mat-list-item (click)="index = 1"> tab 2 </button>
            </mat-action-list>
      </mat-sidenav>
      <mat-sidenav-content>
          <app-tab-content [(index)]=index></app-tab-content>
      </mat-sidenav-content>
    </mat-sidenav-container>

app.component.css

    .side-nav-container {
      position: absolute;
      top: 0;
      bottom: 0;
      left: 0;
      right: 0;
      background: #eee;
    }


    .sidenav {
      width: 200px;
      background: rgb(15,62,9);
    }

    mat-action-list .mat-list-item {
      color : white;
    }

app.component.ts

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

    @Component({
      selector: 'my-app',
      templateUrl: './app.component.html',
      styleUrls: ['./app.component.css']
    })
    export class AppComponent {
      index: number;
    }

tab-content.component.html

       <mat-tab-group [(selectedIndex)]="index" class="header-less-tabs" animationDuration="0ms">
        <mat-tab> Content 1 </mat-tab>
        <mat-tab> Content 2 </mat-tab>
      </mat-tab-group>

tab-content.component.css

    .header-less-tabs.mat-tab-group .mat-tab-header {
      display: none;
    }

tab-content.component.ts

    import { Component, OnInit, ViewEncapsulation, Input } from '@angular/core';

    @Component({
      selector: 'app-tab-content',
      templateUrl: './tab-content.component.html',
      styleUrls: ['./tab-content.component.css'],
      encapsulation: ViewEncapsulation.None
    })
    export class TabContentComponent {

      @Input() index: number = 1;

    }

Answer 2

So this is not perfect in my opinion but its very little code, does the trick and seems to work well with the other features of mat-tabs.

.mat-tab-group {
    flex-direction: row !important;
}

.mat-tab-labels {
    flex-direction: column !important;
}

.mat-tab-label-active {
    border-right: 2px solid $primary-color !important;
}

.mat-ink-bar {
    display: none;
}

Since the relevant classes are rendered outside the scope of the component, you will have to set encapsulation to ViewEncapsulation.None, note: this might meddle with the component styles.

This obviously does not solve the lack of animation but for me it was enough that the active strips gets highlighted which I achieved by simply hiding the original ink-bar and adding a border which mimics it

Answer 3

Wrote angular-vertical-tabs. This simply wraps @angular/material's mat-selection-list, and uses @angular/flex-layout to reorient for different screens sizes.

Usage

<vertical-tabs>
  <vertical-tab tabTitle="Tab 0">
    Lorem ipsum dolor sit amet, consectetur adipiscing elit.
    Mauris tincidunt mattis neque lacinia dignissim.
    Morbi ex orci, bibendum et varius vel, porttitor et magna.
  </vertical-tab>

  <vertical-tab tabTitle="Tab b">
    Curabitur efficitur eleifend nulla, eget porta diam sodales in.
    Lorem ipsum dolor sit amet, consectetur adipiscing elit.
    Maecenas vestibulum libero lacus, et porta ex tincidunt quis.
  </vertical-tab>

  <vertical-tab tabTitle="Tab 2">
    Sed dictum, diam et vehicula sollicitudin, eros orci viverra diam, et pretium
    risus nisl eget ex. Integer lacinia commodo ipsum, sit amet consectetur magna
    hendrerit eu.
  </vertical-tab>
</vertical-tabs>

Output

Full width

Smaller screen

Answer 4

Use the below code for the vertical tab using angular material.

HTML

<div class="container">
  <div id="content">
    <div id="main-content">
      <mat-tab-group>
        <mat-tab label="Tab One">
          Tab One Content
        </mat-tab>
        <mat-tab label="Tab Two">
          Tab Two Content
        </mat-tab>
      </mat-tab-group>
    </div>
  </div>
</div>

        clear: both;

}
