Lightbox2 is a very popular and powerful Drupal module. One of the helpful features is that you can render a Drupal node in a lightbox rather easily in either PHP or HTML. View detailed explanation. The issue is that when you click a link within that lightboxed content, you will lose the lightbox2 templating (e.g., if your lightbox template hides sidebars, they’ll only be hidden when the node loads. If you click a link within the lightbox, the new node will load and sidebars will appear). Read on for a quick fix.
