simple_form.rb

#config/initializers/simple_form.rb
config.wrappers :bs, :tag => 'div', :class => 'form-group' do |b|
  b.use :html5
  b.use :placeholder
  b.use :label_text, :tag=> 'label', :class => 'col-sm-2 control-label'
  b.use :readonly
  b.wrapper :tag => 'div', :class => 'col-sm-10' do |ba|
    ba.use :readonly
    ba.use :desc, :tag=>'p', :class => 'form-control-static'
    ba.use :error, :wrap_with => { :tag => 'span', :class => 'help-inline' }
    ba.use :hint,  :wrap_with => { :tag => 'p', :class => 'help-block' }
  end
end

Why not simply

app/inputs/static_input.rb

class StaticInput < SimpleForm::Inputs::BlockInput
  def input(wrapper_options = nil)
    content_tag :p, object.send(attribute_name), class: "form-control-static"
  end
end

and then

<%= f.input :email, as: :static %>
