Hi there.

I know that there are a lot of solutions that have been discussed for  
this issue here already. However none of them did work for me. Either  
the selected option did work, but not “:include\_blank =\> true” or my  
AJAX-code gots messed-up.

Is there a final solution for this?

Here my code:

\<%= collection\_select(“category\_selection”, “super\_category\_id”,  
@super\_categories, :super\_category\_id, :name,  
@selected\_super\_category\_id,  
{:onChange =\> remote\_function(:update =\>  
“box\_search”,  
:url =\> {:action  
=\> :search\_by\_category},  
:submit =\>  
“category\_selection\_super\_category”) } ) -%\>

Thanks  
David

Hi, could you explain what you’re trying to do exactly so that people  
can chime in?

Hi. I’m trying to generate a HTML select-tag including the selected  
option from a model object.

I’ve tried this with the collection\_select, which does not include the  
selected option. I’ve also tried options\_from\_collection\_for\_select,  
which worked unless a blank option was included.

Thanks  
David
