forms - Rails how to create recursive nested_form_for for child-parent relations -

model is

class menuitem < activerecord::base   belongs_to :menu_item   has_many :menu_items   accepts_nested_attributes_for :menu_items end

how create form ability add dynamically children , children of children if needed (preferably nested_form_for). in other words form shall like:

input   child input     child input (child of child)     add/remove child (child of child of child)   add/remove child (child) add/remove input

clicking add/remove add/remove 1 more according child, how can achieve this?

cocoon should able handle use case fine. need experimenting since deep nesting non trivial.
