Hello Juan Jose,
I am afraid I didn't understand the part of your post marked in red:
>> "When a new notification is showed when the previous one is still on screen, the first one dissapear and the second one shows up as I want, but the first div element don't dissapear and last still when the last one dissapear.
Generally, notifications use animations to show and hide. This means that if you hide the existing notification and show the new one immediately afterwards, there will be time when two animating notifications are visible on the screen. If you want to avoid this, you will need to remove the existing notification from the DOM.
notificationWidget = $(
Let me know if I am missing something.
