\<%= collection\_select(:post, :id, @posts, :id, :title, options ={:prompt  
=\> “-Select categories-”}, :class=\>“category\_dropdown\_list”) %\>

Hi, how would I send the value of the selected item in the  
collection\_select?

I’m trying to use an observe\_field for an input, and in the action I’ll  
perform the steps corresponding to the collection\_select.

Thanks
