Dropdown menu section with multiple links with text and image contents

Hi, I would like a panel to show up when the mouse hover over the header buttons, capable of showing multiple links and a small description write up with an image. 

I don't know how to describe it, It's like a page that shows up when hovered?

The closest reference is to hover over the "Contact" button in the link

Thank you, will refer to the YouTube tutorial!
