What is the Best Way to Implement ngFor in a Multi-Component Setup?

I need to implement ngFor for 10 different components.

Here's an example of what I'm trying to achieve:

<ion-slide class="page-slide" *ngFor="let item of slideArr">
 <ion-card class="page-slide-card">
  <ion-card-content> {{item.title}}
    <component of number x></component of number x>
  </ion-card-content>
 </ion-card>
</ion-slide>

I want each of the 10 components to load on screen without using ngIf. Is there another way to accomplish this?
