Hi there,

I’m using ionic 5 and I want to use contentId with ion-router-outlet’s id attribute.  
However I put my ion-menu that has the contentId inside of a custom component.

How can I expose this contentId to the app’s ion-router-outlet?

I currently am getting the following two error messages in my console:

> Can’t bind to ‘routerLink’ since it isn’t a known property of ‘div’.  
> Menu: must have a “content” element to listen for drag events on.
