I'm looking for an external or abstraction or something to create a
"horizontal umenu" - meaning that the orientation of the unclicked
state is a tall, narrow rectangle, and then when you click it, it
expands horizontally to reveal its menu items.
Also, it would be great if the text appeared up and down:
C | I | I | e
l | t | t | t
i | e | e | c
c | m | m | .
k | 2 | 3 | .
e | | | .
d | | |
