Looking to divide the nested ngfor loop into 3 sections
<div class="row" *ngFor="let row of matrix; index as i">
<div class="col" *ngFor="let col of row; index as j">
<div *ngFor="let placeholder of placeholders | slice:i:j">
<ng-container [ngComponentOutlet]="placeholder.component" >
</ng-container>
</div>
</div>
</div>
Here are a couple of solutions to this issue:
$any
<p *ngFor="let item of data | slice:2:4">
{{ $any(item).parentName }}
</p>
Using bracket notation
<p *ngFor="let item of data | slice:2:4">
{{ item['parentName'] }}
</p>
Implementing a function
slicedData(data : any[]) : any[] {
return data.slice(2,4)
}
<p *ngFor="let item of slicedData(data)">
{{ item['parentName'] }}
</p>
