Select2 inputs for SimpleForm

Select2SimpleForm

Select2SimpleForm is a custom input for SimpleForm which wraps and simplifies the Select2 functionality, without messing around with JS stuff.

Installation

Assuming you are using SimpleForm and a working Select2 plugin (a fast way of doing so is installing and configuring a Rails Select2 plugin, like this one). After having done this, then:

Add this to your Gemfile:

gem 'select2_simple_form'

And this into your app/assets/javascripts/application.js (making sure that the following line have to be placed after Select2 JS):

//= require select2_simple_form

And you're done my dear friend!

Usage

All you're gonna do is to use SimpleForm inputs as: :select2.

with collections

Render a Select2 simple collection (selecting a single item):

<%= f.input :countries, as: :select2, collection: Country.all %>

Render a Select2 multiple collection (selecting several items):

<%= f.input :countries, as: :select2, collection: Country.all, multiple: true %>

with ajax

Render a Select2 performing an AJAX request that finds and shows the data (selecting a single item).

<%= f.input :countries, as: :select2, ajax: 'http://route/to/get/data/for/input' %>

Render a Select2 performing an AJAX request that finds and shows the data (selecting several items).
