Chouti,
To solve your first issue, I would set up your models slightly
different.
class Item < ActiveRecord::Base
belongs_to :sub_category
end
class SubCategory < ActiveRecord::Base
belongs_to :category
has_many :items
end
class Category < ActiveRecord::Base
has_many :sub_categories
has_many :items, :through => :sub_categories
end
in your items controller you can do this
active_scaffold do |config|
config.columns[:sub_category].form_ui = :select
end
This changes it from a subform, and now you only have one drop down
that is visible, and there will no longer be options to create
subcategories.
This does not solve your problem with the form though. There are many
ways to approach getting a category drop down, and then making it work
with javascript. If you would like help with this let me know.
