                    </ng-container>
                </ng-container>
            </ng-container>
        </ng-container>

The problem is that all *ngFor are running infinite times except the very first one . As mentioned in the in link that avoid the calling of methods from template link

I have crossed checked the data in map and loop.. it is limited data but still it is running infinite times I have verified all the data and it is accurate ..

Any help is appreciated
