Rails - Add prompt to country_select

Question

As title suggests, how do I add a prompt using country_select gem?

Currently just to try get it working I tried

<%= f.country_select(:country, { prompt: 'Please select..' }, {prompt: 'Please select..'}, {prompt: 'Please select..'} ) %>

Answer 1

3rd is a option argument in country_select helper so,

<%= f.country_select(:country, your_options_method, {prompt: 'Please select..'}) %>
