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,
