Toggle blind on multiple items.

I have a faq where the answers are blinded down when the question is clicked. What I want to do is have a link that either blinds up or down all the answer-elements on the page. When the link is clicked, it should switch between the text "Show all" / "Hide all" and the link_to_remote should also change. I figure I´ve made a mess out of it as it is. Can I somehow make all this in action or something also?

How should I do this?

# in my controller: def display_all     render(:update) do |page|       page.select('div.answer').each do |answer|         answer.visual_effect(:blind_down, :duration => 0.25, :fps => 100)       end

       page.replace_html :toggle_all, link_to_remote("Hide all", {:url => {:action => :hide_all}}, :id => "toggle_all")     end   end

  def hide_all     render(:update) do |page|       page.select('div.answer').each do |answer|         answer.visual_effect(:blind_up, :duration => 0.25, :fps => 100)       end

       page.replace_html :toggle_all, link_to_remote("Show all", {:url => {:action => :display_all}}, :id => "toggle_all")     end   end

## in my template:

<%= link_to_remote("Show all",                             {:url => {:action => :display_all}}, :id => "toggle_all")%>
