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!
