Thanks, this trick helped me. But I use

config.wrapper_mappings = { boolean: :checkbox }
config.wrappers :checkbox, tag: :div, class: 'checkbox', error_class: 'has-error' do |b|
  b.use :html5
  b.use :label_input

  b.use :hint,  wrap_with: { tag: :p, class: 'help-block' }
  b.use :error, wrap_with: { tag: :span, class: 'help-block text-danger' }
end

When I use

b.wrapper tag: :label do |ba|
  ba.use :input
  ba.use :label_text
end

the inputs adds me a label automatically and just prepends the plain text.
