How to add button to ActiveAdmin's index page

Question

I created a collection action for ActiveAdmin rescource and want to link to it from the resource index page.

But how do I customize the resource index page?

Answer 1

You can create buttons on index page with action_item block:

action_item only: :index do
  link_to 'Button text', post_path(post)
end
