     # # Index as a Grid
     #
     # Sometimes you want to display the index screen for a set of resources as a grid
     # (possibly a grid of thumbnail images). To do so, use the :grid option for the
     # index block.
     #
     # ```ruby
     # index as: :grid do |product|
     #   link_to image_tag(product.image_path), admin_product_path(product)
     # end
     # ```
     #
     # The block is rendered within a cell in the grid once for each resource in the
     # collection. The resource is passed into the block for you to use in the view.
     #
     # You can customize the number of columns that are rendered using the columns
     # option:
     #
     # ```ruby
     # index as: :grid, columns: 5 do |product|
     #   link_to image_tag(product.image_path), admin_product_path(product)
     # end
     # ```
     #
