I want to display particular node content in popup. Is it possible in lightbox 2. i need your help frds.
There are couple of way to achieve this.
Try the Popup module
The popup suite allows builders to popup tooltip-like text, nodes, blocks, menus, forms, views and php-generated content.
You can also use the Overlay Paths module for that.
This is a simple module that enables site builders to use the built-in Overlay for non-admin pages.
Give the module Entity Popup a try. It allows you to show any entity in a popup by providing a menu callback that allows you to load the entity into any popup you desire (Colorbox, Lightbox, …). You need to code a module for your own popup but there are example modules included for Colorbox and for jQuery UI Dialog, which is included in Drupal Core.
