Options_for_select and setting css class values

Hi,

i’m not sure if this is possible using erb (at the very least, I can’t
figure it out by googling or via searching this board), so here
goes…

i’m using erb to make a select box with several hundred
values

it looks something like this:

<%= select_tag ‘controls’, options_for_select(@controls.map {|cpd|
["#{cpd.compound_name}…#{cpd.trimmed_number}"]}), {:class =>
‘superwide’, :size => 20} %>

the above code works great…except for 1 thing.
i’d like to cycle the color of every other tag using css.

obviously, i’d like to use the ‘cycle’ function, but how/where do i
get options_for_select to accept a value for a css-class?
e.g. :class => ‘blue_text’

i’m not even sure if this is possible…

TIA!
