Angular - Component Interaction

How can you combine ng-content with Angular structural directives to conditionally display projected content in named slots?

AUse <code>ng-content</code> with <code>*ngFor</code> to filter content.

BAdd <code>*ngIf</code> directly on <code>ng-content</code> tags.

DWrap projected content in <code><div *ngIf></code> inside the parent component.
