Question: 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?

Answer: 
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")

```
