Not sure what you mean by conditionally... if it's something server side you could just do: <% if this_expression_evaluates_to_true %> put your html here <% end %> The way content_for works is to capture the result of the block (everything in b/n) and save it for later. You can get it back by doing <%= yield :sidebar %> -philip --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
