How to create a dropdown menu ?

Question

I am trying to create a dropdown menu in my application that looks and functions like the one in the attached image. 
 I am unsure how to make the dropdown appear like this without dropdown component 
 
 Can you please help me to achieve this

There are several ways you could accomplish this, gracefully, but none of them will look exactly like the top menu bar built-in to Appian, since it's using its own unique internal functionality.
