Overview

Outputs a country select input, wrapping around a regular country_select helper. Rails doesn’t come with a ‘country_select` helper by default any more, so you’ll need to do one of the following:

• install [the official Rails plugin](github.com/rails/iso-3166-country-select)

• install any other country_select plugin that behaves in a similar way

• roll your own ‘country_select` helper with the same args and options as the Rails one

By default, Formtastic includes a handfull of English-speaking countries as “priority counties”, which can be set in the ‘priority_countries` configuration array in the formtastic.rb initializer to suit your market and user base (see README for more info on configuration). Additionally, it is possible to set the :priority_countries on a per-input basis through the `:priority_countries` option. These priority countries will be passed down to the `country_select` helper of your choice, and may or may not be used by the helper.

Examples:

Basic example with full form context using ‘priority_countries` from config

<%= semantic_form_for @user do |f| %>
  <%= f.inputs do %>
    <%= f.input :nationality, :as => :country %>
  <% end %>
<% end %>

<li class='country'>
  <label for="user_nationality">Country</label>
  <select id="user_nationality" name="user[nationality]">
    <option value="...">...</option>
    # ...
</li>

‘:priority_countries` set on a specific input

<%= semantic_form_for @user do |f| %>
  <%= f.inputs do %>
    <%= f.input :nationality, :as => :country, :priority_countries => ["Australia", "New Zealand"] %>
  <% end %>
<% end %>

<li class='country'>
  <label for="user_nationality">Country</label>
  <select id="user_nationality" name="user[nationality]">
    <option value="...">...</option>
    # ...
</li>
