How to send multiple values to controller using :with option of collection_select

Hi,

Thank u all for replying my previous posts.

I have following problem

I want to send multiple selected values from collection_select using ":with" option to a controller without submitting the form, i have following code

<%= collection_select(:cluster, :CLST_RegionID, regions, :id, :REG_RegionName,                       {:prompt => "Please Select"},                       {:onchange => "#{remote_function(:url => {:action => "update_clusters"},                                                        :with => "'id='+value")}"}) %>

this works fine for single value, when I write ":multiple => true" it is not allowing me to pass multiple values.

what should I change in the above code to passing multiple values to controller?

Please help me out,

Thanks, Shripad
