This feature is about to be merged to master right now (Oct. 2012):

Then you can do something like this to add HTML attributes directly on the input field:

SimpleForm.build :tag => :div, :class => "custom_wrapper" do |b|
  b.wrapper :tag => :div, :class => 'elem' do |component|
    component.use :input, :class => ['input_class_yo', 'other_class_yo']
    component.use :label, :"data-yo" => 'yo'
    component.use :label_input, :class => 'both_yo'
    component.use :custom_component, :class => 'custom_yo'
  end
end
