Thanks, but I figured it out.

In case people are interested...what I meant was this:

In my example I have 12 items (both make and model nodes) and so three columns should be 4 each. I don' t want to break up a make node though so the actually output groups them into columns of 5, 4 and 3. Having 4 items in each column would cause the "accord" to in a different column then the rest of the hondas. Same with the tundra/toyotas. Is that more clear?

The solution I came up with is the following snippit. I am new to XML and XSLT so if anyone sees any potential problems or knows a better way (maybe without iterating through all the cars three times...) with this please let me know. It seems to work well though for me.

Hi.

When you say "Ideally it wouldn't break the makes up" what does that
mean? I had to code a template where it would break a listing on
headers when the headers were within 5 list items of the midpoint, but
if the header was further than that from the midpoint then it would
break at the midpoint and add a continuation header to the top of the
second column.

I actually ended up doing the logic to find the break point in several
steps before starting the output run, then spitting out the column break
using d-o-e when I encountered the break point, although I know that
idea will make XSL idealists shudder.

I think in order to give a good answer one would need to know more about
your column breaking rules.
