This one has a dropdown for subjects (math, science), and shows a list of
courses in the selected subject:
<%= form_tag('courses/by_subject', :remote => true, :method => "get",
> :data => { :type => "script" }, :id => 'course_search') do %>
> <%= select_tag( "subject_id", options_for_select(Subject.all.collect
> {|p| [ p.name, p.id ] }),:prompt => 'Select Subject' ) %>
> <%= submit_tag "Search" %>
> <% end %>
> <div id="course_list">
> <%= render 'courses' %>
> </div>
You may not need the Subject.all.collect part if you have an array of
choices.
