When defining a re-usable modal container, I could not get the ‘title’ attribute to appear when set on the parent template’s use of the component.
I was using a modal with a map sibling, as
template: '<div id="map-canvas"></div><modal-container title="Section Notes"></modal-container>'
I figured out the child component needed to use the input decorator on the ‘title’ property. So in modal-container.component.ts, in the export class ModalContainerComponent
definition
title: string;
became
@Input() title: string;
and it worked.
