#country_select(object, method, priority_or_options = {}, options = {}, html_options = {}) ⇒ Object

Generate select and country option tags for the given object and method. A common use of this would be to allow users to select a state subregion within a given country.

object - The model object to generate the select for method - The attribute on the object options - Other options pertaining to option tag generation. See

`region_options_for_select`.

html_options - Options to use when generating the select tag- class,

id, etc.

Uses country_options_for_select to generate the list of option tags.

Example:

country_select(@object, :country, {priority: ['US', 'CA']}, class: 'country')

Note that in order to preserve compatibility with various existing libraries, an alternative API is supported but not recommended:

country_select(@object, :region, ['US', 'CA'], class: region)

Returns an ‘html_safe` string containing the HTML for a select element.
