If you only have these two cities you can use normal html

<select id="city_id" name="city_id">
<option value="1">Lisbon</option>
<option value="2">Madrid</option>
</select>

If you fetch the cities from you database you can do

select_tag ‘city_id’, options_for_select(@cities.collect{ |u| [u.name, u.id] })

This would generate something like:

<select id="city_id" name="city_id">
  <option value="1">Lisbon</option>
  <option value="2">Madrid</option>
</select>

Do not be afraid to use html. The most simple solution is the best solution.
