loading nodes with Ajax/jQuery Assume that we have a list of titles on the left and a div on the right side of the page that displays posts. when I click one of the titles it first removes content of that div and then loads node content. how can I do this? is there any module or function to do that?
You could look at the Quick Tabs and Vertical Tabs modules.  Otherwise you could write your own custom module if you had super specific needs and are proficient with drupal menu callbacks and php and of course jQuery.
