Dynamically add a component to a child using the directive

Question

Attempting to place a component dynamically to a child using a directive.

Component (as a template):

@Component({
  selector: 'ps-tooltip',
  template: `
    <div class="ps-tooltip">
      <div class="ps-tooltip-content">
        <span>{{content}}</span>
      </div>
    </div>
  `
})
export class TooltipComponent {

  @Input()
  content: string;

}

directive:

import { TooltipComponent } from './tooltip.component';

@Directive({
  selector: '[ps-tooltip]',
})
export class TooltipDirective implements AfterViewInit {

  @Input('ps-tooltip') content: string;

  private tooltip: ComponentRef<TooltipComponent>;

  constructor(
      private viewContainerRef: ViewContainerRef,
      private resolver: ComponentFactoryResolver,
      private elRef: ElementRef,
      private renderer: Renderer
  ) { }

  ngAfterViewInit() {
    // add trigger class to el
    this.renderer.setElementClass(this.elRef.nativeElement, 'ps-tooltip-trigger', true); // ok

    // factory comp resolver
    let factory = this.resolver.resolveComponentFactory(TooltipComponent);

    // create component
    this.tooltip = this.viewContainerRef.createComponent(factory);
    console.log(this.tooltip);

    // set content of the component
    this.tooltip.instance.content = this.content as string;
  }
}

The problem is that this creates a sibling and I want a baby (see below)

result:

<a class="ps-btn ps-tooltip-trigger" ng-reflect-content="the tooltip">
  <span>Button</span>
</a>
<ps-tooltip>...</ps-tooltip>

desired result:

<a class="ps-btn ps-tooltip-trigger" ng-reflect-content="the tooltip">
  <span>Button</span>
  <ps-tooltip>...</ps-tooltip>
</a>

Thanks in advance for your help!

Even the dynamic component is inserted as a lifting element, you can still move the element to the desired location using:

this.elRef.nativeElement.appendChild(this.tooltip.location.nativeElement);
