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.
