It looks and feels exactly like rails_admin_nestable but uses jquery Nested Sortable and awesome_nested_set or glebtv-mongoid_nested_set instead of Nestable and Ancestry.

Designed and tested with glebtv-mongoid_nested_set but should also work with awesome_nested_set (untested)

Bonus features:

• special case support for enabled column with rails_admin_toggleable
• special case support for cover and image columns

Add this line to your application's Gemfile:

gem 'rails_admin_nested_set'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_admin_nested_set

In model:

Add in your config/initializers/rails_admin.rb initializer the configuration:

RailsAdmin.config do |config|
  config.actions do
    # root actions
    dashboard                     # mandatory
    # collection actions
    index                         # mandatory
    new
    export
    history_index
    bulk_delete
    # member actions
    show
    edit
    delete
    history_show
    show_in_app

    # Add the nested_set action for configured models
    nested_set
  end
end

acts_as_nested_set
rails_admin do
    ...
    nested_set({
        max_depth: 1,
        toggle_fields: [:enabled],
        thumbnail_fields: [:image, :cover],
        thumbnail_size: :thumb,
        thumbnail_gem: :paperclip, # or :carrierwave
    })
end
