Are there another ways of representing a array type field in rails_admin?
Now it looks: - alsace - france - french - pinot blanc - dry
where array items are separated by - symbol.

I introduced transient fields for this:
class KnowHow
include Mongoid::Document
SPLITTER = ','
field :category, type: String
field :content_array, type: Array
def content
(content_array || []).join(SPLITTER)
end
def content=(items)
if items.present?
self.content_array = items.split(SPLITTER).map(&:strip).reject(&:blank?)
else
self.content_array = []
end
end
rails_admin do
field :category
field :content
end
end
