class ActiveAdmin::Views::IndexAsGrid
# 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 “‘
