Using extra parameter in ngSwitchCase

Question

First of all, want to emphasize that I had already have a look at many pages e.g. Two switch case values in angular but they cannot fix my problem.

I have the following

Answer 1

Create another ng-container inside with the loading condition.

<ng-container [ngSwitch]="i">
    <ng-container *ngSwitchCase="0">
        <ng-container *ngIf="loading">
            // do stuff
        </ng-container>
    </ng-container>
</ng-container>
