There is no immediate plans for the notification component for the official release as it's stated in the official roadmap:
Until an official Notification component is implemented, you can use the Popup component to achieve a similar behavior. The most important functionality (absolute positioning and boundary detection) is already available. With that in mind, you can easily position the popup on element hover:
public ngOnInit(): void {
this.renderer.listenGlobal("document", 'mousemove', e => this.toggle(this.elementOffset(e.target)));
}
Here is a POC demo:
P.S. Note that in Angular 4, there will be only listen
method. More details in this StackOverflow answer: https://stackoverflow.com/a/35082441/324224
