Hi,   So I have a controller action that populated an instance variable @links. The Links are rendered as partials and displayed down the page in a div. What I want to do is: on clicking a link (from a dropdown menu) go to that same action, repopulate @links and replace the content in the page div with the new content. Is this a link_to_remote with an :update option, an rjs template with replace_html or something else? Thanks for you help.

This would be a select which has an observer on it.

If you look at rjs, you can do a page.replace_html div, render :partial => 'partial'

You can call this from a link_to_remote, have the controller repopulate the @links and let rjs do the trick.

You could also do it in the controller to replace the html like so:

if request.xhr?   render :update do |page|      page.replace_html div, :partial => 'partial'   end end
