Angular 2 ngSwitchCase, OR operator not working

If you evaluate 'd' || 'e' || 'f' the result is 'd' and when options is not 'd', then it doesn’t match. You can’t use ngSwitchCase that way.

This would work:

    <ng-container [ngSwitch]="true">
        <ng-container *ngSwitchCase="options === 'a'">Code A</ng-container>
        <ng-container *ngSwitchCase="options === 'b'">Code B</ng-container>
        <ng-container *ngSwitchCase="options === 'c'">Code C</ng-container>
        <ng-container *ngSwitchCase="options === 'd' || options === 'e' || options === 'f'">Common Code</ng-container>
        <ng-container *ngSwitchDefault>Code Default</ng-container>
    </ng-container>
