title: Simple Form I18n labels
body: <p>Hi everyone in my app I build a search box. It looks like this:</p>
  
  <pre><code>= simple_form_for :cars, {url: cars_path, method: :get} do |f|
    = f.input :handover_location, collection: Location.all.map{|hl| [hl.name, hl.id]}
    = f.input :return_location, collection: Location.all.map{|rl| [rl.name, rl.id]}
    = f.input :car_class, collection: CarClass.all.map { |c| [c.name, c.id] }, include_blank: true
    = f.submit 
  </code></pre>
  
  <p>And now i don't know how to translate this labels with I18n. How can I do this?</p>
