[jQuery] Gmail "Hidden From View" Notification

[jQuery] Gmail "Hidden From View" Notification


Hello there.
I'm trying to create a function for a website that is similar to a
hidden from view notification from Gmail. In Gmail when you are
reading a long email conversation, it pops up a small tab with a name
and an arrow to indicate there is more to read but it's hidden from
view.
I would like to know if there's a way to duplicate that using jQuery?
