Hi,

I have something as such:

collection\_select(:obj, :types, @types, :id, :name, {}, {:multiple =\>  
true, :size =\> 4})

and I want the row colors to alternate. This is easy to do when manually  
building the options tags (as you just add a class name for every other  
tag), but I cant figure out how to do it the rails way

Any suggestions?

Thanks.
