Answer 1

I was using a select box as part of a Search bar, so wanted to have the default first option selected on first presentation of the form, but then retain the chosen option thereafter. This works great:

<% styles = Styles.all.sort %>
<%= form_tag styles_path, :method => 'get' do %>
    

        Search: style
        <%= select_tag :search_style, options_for_select(styles, selected: params[:search_style]) %>
         with colour
        <%= text_field_tag :search_color, params[:search_color] %>
        <%= submit_tag "Search" %>
    
<% end %>
