Menus that only drop down when you hover
There is no hover on a touchscreen and no hover on a keyboard. A hover-only dropdown keeps everything inside it out of reach.

Menus that only drop down when you hover
What it actually is
The dropdown that opens on mouse-hover and nothing else.
Who it shuts out
There is no hover on a touchscreen and no hover for someone using a keyboard. So phone users and keyboard users can never open the menu at all, and everything inside it is simply out of reach.
