Answer 2

You can't add more than one HTML file.

What you can do is, use *ngIf or *ngSwitchCase to show only parts of the template if that is your intention. Then you have only one template html file.

Then html of your template will be something like this:

<div *ngIf="YOUR_CONDITION">View 01</div>
<div *ngIf="YOUR_CONDITION">View 02</div>
