How can I use select\_tag to

1. Have a prompt like “Select a Value” ( selected by default )

I tried this but did not work:

\<%= select\_tag :current\_course,  
options\_for\_select( Course.find(:all).map {|p|  
[p.title,p.id]} ),  
{ :prompt =\> “Select a Value” }  
%\>

1. Generate a ‘selected’ event so that some action can be done like  
submit the form or refresh the page?

Thanks in advance
