error, when I try to use *ngFor in it. I've ensured my syntax should be correct, and that data from the component is visible, but I'm just not sure if I either:
A: Have configured my .module file correct, or
B: The component doesn't initialize the module, as it is loaded through the NavItemsService.



The reason for this is because I want to make a dropdown with a list that is the length of whatever data I receive from a Db, with expandable and more.
