Xmonad Layout with vertically stacked secondary tiles

Question

I'm looking for a layout for use on a portrait oriented monitor that would look roughly like this (warning bad ascii art):

|------------|
|            |
|  master    |
|            |
|------------|
| secondary  |
|------------|
| secondary  |
|------------|
| secondary  |
|------------|

Answer 1

I found a good option in xmonad-contrib:

myLayoutHook = Column 2.0 ||| ...

play with the number 2.0 to suit your screen size
