Using ngIf and ngFor in option

I want to use ngIf and ngFor in one line. I know it is not possible but is there any other method to do this?

Here is my code:

<option *ngIf="tmpLanguage.id!=languages.id"
*ngFor="let tmpLanguage of languages" [ngValue]="tmpLanguage.id">

Only one structural directive is allowed on one element at a time.

As a workaround you can use <ng-container> which is not stamped to the DOM

<ng-container *ngFor="let tmpLanguage of languages">
  <option *ngIf="tmpLanguage.id!=languages.id"  [ngValue]="tmpLanguage.id" >{{tmpLanguage.identificatie}}</option>
