Select2 is a jQuery based replacement for select boxes. It supports searching, remote data sets, and infinite scrolling of results.
The select2-rails gem integrates the Select2 jQuery plugin with the Rails asset pipeline.
Add select2-rails to your Gemfile and run bundle install:
Add the following to your app/assets/javascripts/application.js:
To add select2-full.js instead of select2.js, add the following instead :
Add to your app/assets/stylesheets/application.css:
If you are using Twitter Boostrap you need to also require the bootstrap theme CSS in addition to the above require.
*= require select2-bootstrap
To apply the theme, tell Select2 to do so by passing bootstrap to the theme option when initializing Select2:
$( "#dropdown" ).select2({
theme: "bootstrap"
});
The select2-rails now supports multiple languages.
Add the following to your app/assets/javascripts/application.js:
//= require select2_locale_"any possible language"
To apply the language, pass whatever language you'd like to use to the language option when initializing Select2:
$( "#dropdown" ).select2({
language: "zh-TW"
});
Possible languages:
af, ar, az, bg, bn, bs, ca, cs, da, de, dsb, el, en, eo, es, et, eu, fa, fi, fr, gl, he, hi, hr, hsb, hu, hy, id, is, it, ja, ka, km, ko, lt, lv, mk, ms, nb, ne, nl, pa, pl, ps, pt, pt-BR, ro, ru, sk, sl, sq, sr, sr-Cyrl, sv, th, tk, tr, uk, vi, zh-CN, zh-TW

IE8 doesn't support some unescaped Unicode character and need to quote keys in object literals You need some configurations for Uglifier to do the work. Add to your config/environments/production.rb
require 'uglifier'
config.assets.js_compressor = Uglifier.new(output: {ascii_only: true, quote_keys: true})
From v2.1.0 on, select2-rails's version will match the version of Select2 it uses.
The last number of the version is the patch version specific to the gem. For example, for a version of the form 2.x.y, 2.x is the release of Select2 we should be compatible with, and y is the patch version specific to the gem (ie. to resolve any gem-specific issues that crop up).
