Rails - May 2006 - expanding details examples?

I''m currently using page.visual_effect :toggle_appear to toggle the  
appearance of details associated with an order.  As I am inserting  
the detail data prior to making it visible, this method is not  
appropriate (it also loads the data on hide).

I was thinking I could change the hide/show href each time it is  
clicked, or even store a value on the page and toggle it each time  
it''s clicked - but it seems like there must be a better solution.

Here''s my makeshift .rjs template:

   page.replace_html "items" + params[:id].to_s, :partial =>  
''order_item'', :collection => @order_items
   page.replace_html "item_footer" + params[:id].to_s, :partial =>
''order_item_form''

   page.replace_html "comments" + params[:id], :partial =>  
''order_detail'', :collection => @order_details
   page.replace_html "comment_footer" + params[:id].to_s, :partial
=>
''order_comment_form''

   page.visual_effect :toggle_appear, ''item_container'' +
params
[:id].to_s, ''duration'' => 0.5

All of the RJS tutorials / examples I''ve been able to find are quite  
basic - is there a good place for information on this stuff?

Thanks in advance,
