Is there any way to use select inside a hidden div block with a model  
object for the select items ? I have the block showing and hiding OK  
with observe\_field, but the variable I’m using to see whether to show/  
hide seems to be the only one allowed by the :with option to  
observe\_field, so I can’t see a way to get the model variable to the  
select box. I tried leaving it as it was before the observe\_field and  
partial, but it doesn’t see the variable anymore to populate the  
choices…

Please help.

I think you will need to show us some view code. The minimum that  
shows the problem please.
