how write *ngfor this? ngfors need in same div or sub element of main ngfor?

the ngfors have are:

*ngfor="let datesofinterest of alldatesofinterests" *ngfor="let dataitem of datesofinterest.dataitems" *ngfor="let listvalue of daysofinterest.dataitems.listvalues" 

you can have 1 *ngfor on single element. in second ngfor can use declared dataitem variable first ngfor. can use <ng-container> elements if don't want pollute generated html divs not rendered.

<ng-container *ngfor="let dataitem of datesofinterest.dataitems">    <ng-container *ngfor="let listvalue of dataitem.listvalues">      {{listvalue.name}}    </ng-container>  </ng-container>
