Theming and customization

RailsAdmin uses a sass release of bootstrap for CSS, and bootstrap/jquery-ui for JS.

For custom theming (application scoped), simply override these files in your app:


Don't forget to re-compile your assets or simply delete the content of your tmp/cache folder. Some additional steps might be required, as others reported here:

RailsAdmin uses jquery-pjax ( to load pages instead normal HTTP requests, use $(document).on('rails_admin.dom_ready', function(){ /* your js code here */ }); instead jQuery's default on ready function $(function(){ /* your js code here */ }); to check if page is loaded. It will work to both normal and pjax requests.

To create a distributable theme

rails plugin new rails_admin_<__THEME_NAME__> -m --skip-gemfile --skip-bundle -T -O --full

Then add to your application Gemfile (before RailsAdmin):

gem 'rails_admin_<__THEME_NAME__>', :path => '../rails_admin_<__THEME_NAME__>'

Inside your rails_admin application config/application.rb, just after Bundler.require:


This will allow for convenient live development testing.

Please follow the convention: rails_admin_ prefix for all RailsAdmin related gems.

Once done, upload it on Github with a valid gemspec (change authors, email and project descriptions) to share your work.


Put all the real theming in theming.css.scss. It can be regular CSS, LESS or SCSS

Note that if you choose to use SCSS, you can:

  • modify all the mixins provided by rails_admin and bootstrap and add others for you to use in mixins.scss. (available mixins here)
  • modify all the variables provided by rails_admin and bootstrap and add others for you to use in variables.scss. Note that the variables in variables.scss are imported before Bootstrap's variables which all have set the !default flag. This effectively means that you can customize chained variables by just assigning a custom value to the first one instead of the need to override each single one. E.g. you do not have to override $btn-success-bg, $label-succes-bg and $progress-bar-success-bg but only assign a custom value to $brand-success. (available variables here)
  • In theming.scss:
    • use all mixins and variables. (your owns, Bootstrap's and RailsAdmin's)
    • include any other .scss file with @import rails_admin/themes/__THEME_NAME__/my_scss_file and organize your the rest of your theme the way you want.


Use anything you want that the asset pipeline supports: regular JS, includes, Coffee, ..


You can use any image available to the asset pipeline.

Use a theme

In your Gemfile:

gem 'rails_admin_example_theme', :git => 'git://'

Inside config/application.rb, just after Bundler.require:

ENV['RAILS_ADMIN_THEME'] = 'example_theme'
