Sorry, but I no longer work on ActiveAdmin often enough to justify mantaining this gem. Take it as it is. If you are interested to update and maintain the gem, please let me know! ❤️
Extra candies for your ActiveAdmin apps.
Add activeadmin-extra to your Gemfile:
   gem 'activeadmin-extra', github: 'stefanoverna/activeadmin-extra'Replace active_admin stylesheets and javascripts with:
   @import "active_admin/extra/base"   #= require active_admin/extraSpice up your admin forms with these brand new inputs:
String field with a larger font.
   ActiveAdmin.register Page do
     form do |f|
       f.input :name, :as => :title
     end
   endThe infamous jquery combobox. To use add to your Gemfile:
   gem 'chosen-rails', group: :assetsand then in your assets:
   #= require chosen-jquery   @import "chosen"Usage:
   ActiveAdmin.register Product do
     form do |f|
       f.input :material, as: :chosen, create_option: true
     end
   endFor the create_option alternative use koenpunt's fork.
Number with unit of measure symbol
   ActiveAdmin.register Product do
     form do |f|
       f.input :price, :as => :measure, :symbol => '€'
     end
   endA row of numeric inputs side by side. Basic usage:
   ActiveAdmin.register Box do
     form do |f|
       f.input :height, :as => :numbers_set # default displays a height_min and a height_max field
     end
   endMultiple options:
   ActiveAdmin.register Box do
     form do |f|
       f.input :height, :as => :numbers_set, :numbers_set => [:mm, :in, :ft]
