Tree-style navigation for RailsAdmin.

Add this line to your application's Gemfile:

gem 'rails_admin-treeview'

And then execute:

$ bundle

Be sure to have rails_admin gem installed.

Configure your model to use Treeview in rails_admin.rb:

RailsAdmin.config do |config|
  config.model Category do
    treeview true
  end
end

Note that your model should implement these methods to use Treeview:

• roots class method that returns all root elements;
• children instance method that returns all of the object's child items.

Tree could be rendered expanded or collapsed. In order to be able to change this, copy and edit app/views/layouts/rails_admin/_navigation.html.haml by running a generator:

rails g rails_admin:treeview

Now you could pass true of false to the treeview helper to render tree expanded or collapsed.
