Prompt in select_tag

In my application in user registration I have a country picker..

<%= select(:user, :country, options_for_select(@COUNTRIES)) %>

And I want to add a prompt as a first default value (something like "--- select country ---"). Where and how should I put this option?

collection_select(:product,
  :category_id,
  Category.all,    
  :id,    
  :title,    
  {:prompt => true}
)

collection_select(:product,    
  :category_id,    
  Category.all,    
  :id,    
  :title,    
  {:include_blank => 'Please Select'}
)

both of these result in the same html, but the first one will not include the 'Please Select' option when you return to edit the previously created Product

Use the FormHelper :prompt

select(:user, :country, options_for_select(@COUNTRIES), {:prompt => "--select county--"})

You can also give customized prompt value like this

select(:user, :country, options_for_select(@COUNTRIES), :prompt=>"select User name")

Very simple:

select(:user, :country, options_for_select(@COUNTRIES), :prompt=>true)

For the prompt "Please select", or this for your custom text:

select(:user, :country, options_for_select(@COUNTRIES), :prompt=>"Select country")

Also note that @COUNTRIES is wrong, an instance variable should be lowercase - @countries, a contant would just be COUNTRIES.
