Drupal Views. Vertical groups.

Hi,

I'd like to do, using views, something like:

i.e., I'm trying to display nodes vertically grouped by a taxonomy grouping field.

I've achieved -so far- displaying nodes in columns but not their groups:
Grouping Field #1
Node #1 Node #3 Node #5
Grouping Field #2
Node #2 Node #7 Node #8 Node #9

Thanks in advance,

Fernando
