    # # Index as a Block
    #
    # If you want to fully customize the display of your resources on the index
    # screen, Index as a Block allows you to render a block of content for each
    # resource.
    #
    # ```ruby
    # index as: :block do |product|
    #   div for: product do
    #     resource_selection_cell product
    #     h2  auto_link     product.title
    #     div simple_format product.description
    #   end
    # end
    # ```
