How to use this gem in custom active admin form page?

[pawlarius]

Is it possible to use searchable in custom Active Admin page?
If yes, how to do it?

All the docs examples is using the normal page like this ActiveAdmin.register "Model Here".

If I try to register custom page, searchable_select won't work in this form 🤔

ActiveAdmin.register_page 'Product' do
  page_action :create_product, method: :post do
  end

  content do
    confirm_submit = 'return confirm("Do you really want to create this product?")'
    form_for :data, url: admin_product_create_product_path, html: { onsubmit: confirm_submit }, method: :post do |f|
    
    # 1. This doesnt work.
    f.input(:additional_category,
            as: :searchable_select,
            ajax: { resource: Product })
    
    # 2. This doesnt work either.
    # f.input(:product_id,
    #   as: :searchable_select,
    #   ajax: { resource: Brand, collection_name: :products })
  end
end

Try using the active_admin_form_for helper instead of form_for. This appears to work in a short test I just did.
