ngSwitchCase - Adds/removes DOM sub-trees when the nest match expressions match the switch expression.
Example
<container-element [ngSwitch]="switch_expression">
<some-element *ngSwitchCase="match_expression_1">...</some-element>
<some-element *ngSwitchCase="match_expression_2">...</some-element>
<some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
<ng-container *ngSwitchCase="match_expression_3">
<!-- use a ng-container to group multiple root nodes -->
<inner-element></inner-element>
<inner-other-element></inner-other-element>
</ng-container>
<some-element *ngSwitchDefault>...</some-element>
</container-element>
