Is there any method for getting the current iteration (for changing row  
colors) in the category partial?

\<%=render(:partial =\> “category”, :collection =\> @categories)%\>

thanks,

Use the variable category\_counter in your partial.

Andy,

The cycle method is a great way to do this. Here is an example:

Then just style ListLine0 and ListLine1.
