I'm looking to change the flow of the DDR mega menu (using the Mega2DNN template). At the moment, items go across in rows - this leaves huge gaps when some pages don't have subpages and some have lots.

eg at the moment it's

Item1     Item2     Item3
Item4     Item5     Item6

I would like to change it so that it works like the DNN site one - the items go vertically down columns like so

Item1     Item3     Item5
Item2     Item4     Item6

Any advice?

Armand, that is incredibly kind of you :-)

 Do let me know if there's a better approach to this, using another template if required? I'm less good at XSLT than CSS, so I can pretty much rework CSS as much as needed, but struggle a little with the other :-)

thanks
Anna
