.locale {
  float: right;
  margin: -0.25em 0.1em;

edit app/controllers/store_controller.rb
  def index
    if params[:set_locale]
      redirect_to store_url(:locale => params[:set_locale])
    else
      @products = Product.order(:title)
    end
  end
edit app/views/layouts/application.html.erb
  <div id="banner">
    <%= form_tag store_path, :class => 'locale' do %>
      <%= select_tag 'set_locale', 
        options_for_select(LANGUAGES, I18n.locale.to_s),
        :onchange => 'this.form.submit()' %>
      <%= submit_tag 'submit' %>
      <%= javascript_tag "$('.locale input').hide()" %>
    <% end %>
    <%= image_tag("logo.png") %>
    <%= @page_title || t('.title') %>
