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 country_select gem
  • 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

Formtastic supports both 1.x and 2.x of stefanpenner/country_select, but if you're upgrading from 1.x, they behave quite differently, so please see their upgrade instructions.

By default, Formtastic includes a handful of English-speaking countries as "priority countries", 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 (country_select 1.x)


<%= 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>

:priority_countries set on a specific input (country_select 2.x)


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

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