<option value="3">Chicago</option>
<option value="4">Detroit</option>
<option value="5">Washington</option></select>

Answer 1

Properly formed select format:

select(object, method, choices, options = {}, html_options = {})

Something like that:

<%= form.select :obj, :city, Picture::CITIES, {:onchange => remote_function(:url => {:action => 'update_universities'}, :with => '')} %>
