#Add this new method

#after def attributes_table
def attributes_table_for_resource(specified_resource, *args, &block)
  panel(I18n.t('active_admin.details', :model => "#{specified_resource.class.name} #{specified_resource.id}")) do
    attributes_table_for specified_resource, *args, &block
  end
end

#How to use it:

#app\admin\myresource.rb
ActiveAdmin.register MyResource do

  show do |myresource|
    attributes_table do
      row :name
      row :price do |myresource|
        number_to_currency(myresource.price)
      end
    end
      
    myresource.nested_resources.each do |nested|
      attributes_table_for_resource(nested) do
        row :description
        row :created_at do |nested|
          nested.created_at.strftime("%d/%m/%Y")
        end
      end
    end
