In order to render error messages that are not connected with any of the visible fields you can use:

= f.error :field_name

Example, order needs at least one item

= simple_form_for @order do |f|
  = f.error :items # here error message about no associated items will be rendered
  = f.simple_fields_for :items do |item|
    = render item
