Pass an array through params

[exAspArk]

Hi! How may I pass the array of arrays to collection?

When I'm trying to do like this:

f.input :ids_in, as: :check_boxes, collection: [
  ['arr1', [1, 2, 3]],
  ['arr2', [4, 5, 6]]
]

I get ids = ["1 2 3"].

Maybe formtastic could recognize the array and somehow populate the inputs?

if choice.kind_of?(Array)
  choice.each do |choice_item|
     builder.check_box_tag(...) 
     # hidden_field_tag 'model[ids][]', value, id: "model_ids_#{value}"
  end
end

I'm not exactly sure what you're expecting as HTML output. If you could create a pull request with a few failing specs to illustrate your idea, I'd be happy to help make progress. Closing for now.
