ActiveAdmin Select2

Description

Incorporate Select2 JQuery into your ActiveAdmin apps.

Installation

Add activeadmin, jquery-rails and select2-rails to your Gemfile:

   gem 'activeadmin'
   gem 'jquery-rails'
   gem 'select2-rails'

And add activeadmin-select2 to your Gemfile:

   gem 'activeadmin-select2', github: 'NechiK/activeadmin-select2'

Add the activeadmin-select2 calls to the active_admin stylesheets and javascripts with:

   @import "active_admin/select2/base";

   #= require active_admin/select2

Usage

Filters

Standard :select filters will automagically be converted to Select2 filters. If you want a multi-select combo-box then use:

   ActiveAdmin.register Products do

      filter :fruits, as: :select2_multiple, collection: [:apples, :bananas, :oranges]

   end

Select Lists

To use a Select2 style list simply change from :select to :select2 or :select2_multiple

   ActiveAdmin.register Products do

     form do |f|
       f.input :fruit, as: :select2
     end

     form do |f|
       f.inputs "Product" do
         f.has_many :fruits, allow_destroy: true, new_record: "Add Fruit" do |e|
           e.input :fruit, as: :select2_multiple
         end
       end
     end

   end
