Is there a way to show a notification in the top (WhatsApp style)

Hi Ionic community

I’m beginner with this framework and I was wondering if it’s possible to show notifications in an application as WhatsApp or Facebook does (in the top of the page).

I was trying to make it with modals or popover, but it i can’t keep working with the current page if I show the popover/modal, so I don’t know if I need to make if purely with CSS…

Have someone did this in the past with Ionic 2?
