Using ngIf and ngFor in option [duplicate]

Answer 1

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

Answer 2

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>
</ng-container>
