here's the code that I tried:
***HTML***

```
<ng-container [ngTemplateOutlet]="room"></ng-container>

<ng-template #room1>
   test 1
</ng-template>

<ng-template #room2>
    test 2
</ng-template>

<ng-template #room3>
     test 3
</ng-template>

```

***TS***

```
room = 'room1';

```

What I'm trying to do is to display the template based on the variable for example.
`room = 'room1'` then it will display only the template `#room1`.

But I'm getting an error which is this one: `Error: templateRef.createEmbeddedView is not a function`
