SF CollectionSelectInput monkey patch

gistfile1.rb

# This is a monkey patch for the SimpleForm issue (actually it's a Rails' collection_select issue)
# of adding attributes to select options. Downside is that you loose value/label_method options, 
# but that's easily replacable by using map on the collection (and should be done in some decorator anyways).
# See here for more details about the issue: https://github.com/plataformatec/simple_form/issues/188
module SimpleForm
  module Inputs
    class CollectionSelectInput < CollectionInput
      def input
        @builder.select attribute_name, collection, input_options, input_html_options
      end
    end
  end
