Append hardcoded value in rails2 f.select_tag

Rails

Hi,

I have a dropdown in my rails partial which onchange calling a remote
function…I am using rails2.3 verison… In the drop down I am
retreiving
list of students like this…

<%= select :students, :id,
                     @students.map {|s| [s.name, s.id] },
                     {:prompt => "Select A Student"},
                     {:onchange => "#{remote_function(
                             :url => { :action => 'type' },
                             :method => 'get',
                             :with => "'stud_id='+value",
                             :before => "Element.show('loader')",
                             :success => "Element.hide('loader')"

)}"}
%>
This is working fine… I get list of students with their ids as
values…
But I need to add one more option as “All students” to the dropdown so
that
I can view the details of all the students. How would I achieve it.
Please
put your thoughts on this as I am new to rails and learning it…
