# = 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.
#
# index :as => :grid do |product|
# link_to(image_tag(product.image_path), admin_products_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 colums that are rendered using the columns
# option:
#
# index :as => :grid, :columns => 5 do |product|
# link_to(image_tag(product.image_path), admin_products_path(product))
# end
#
