Here is a selection in a partial form:

<%= f.association :standards, :collection => Standard.active_std.all(:order => 'name'), :label_method => :name, :value_method => :id, :prompt => "Choose std", :label => "Std：", :include_blank => true %>

The code above displays 5 line options by default. What do I do if I want to only display one option?

Thanks.
