Injecting component to ng-container? (load ng-template from file)

I'm trying to build a simple tabs-menu in my Angular app.

parant.component.html:

<div>
  <button (click)="selectTab(1)">Tab1</button>
  <button (click)="selectTab(2)">Tab2</button>

  <ng-container *ngTemplateOutlet="(selected == 1) ? template1 : template2">
  </ng-container>

  <ng-template #template1>I'm page 1</ng-template>
  <ng-template #template2>I'm page 2</ng-template>
</div>

parant.component.ts:

public selected = 1;
public selectTab(tabName) {
  this.selected = tabName;
}

This is working fine, as long as the <ng-template> is part on the same page html. Now my pages (the content of #template1 and #template2) become complex and I want to move them to separate components.

How could I inject component into <ng-container>??

To inject a Component into <ng-container>, you didn't need to use *ngTemplateOutlet, instead use *ngComponentOutlet.

You can see the full API at: NgComponentOutlet

tab1.component.html:

<p>tab1 works!</p>

tab2.component.html:

<p>tab2 works!</p>

parent.component.html:

<div>
  <button (click)="selectTab(1)">Tab1</button>
  <button (click)="selectTab(2)">Tab2</button>

  <ng-container *ngComponentOutlet="activeTab">
  </ng-container>
</div>

parant.component.ts:

import { Tab1Component } from './tab1.component';
import { Tab2Component } from './tab2.component';
...

public activeTab = Tab1Component;

public selectTab(tabName) {
  if (tabName == 1) {
    this.activeTab = Tab1Component ;
  }
  else if (tabName == 2) {
    this.activeTab = Tab2Component ;
  }  
}

And don't forget to add these dynamic components to the entryComponents section.

app.module.ts:

import { Tab1Component } from './tab1.component';
import { Tab2Component } from './tab2.component';
...
@NgModule({
  ...
  entryComponents: [
    Tab1Component,
    Tab2Component,
    ...
