Ishai Sagi has published a Beta1 on an enhanced content query web part. It is basicly a web part that inherits from Content By Query web parts and then adds some neat functions. What caught my eye first was the abillity to show a contex menu for each item:
Earlier we have seen a few posts on how to add new item styles and customize the query items, but nothing like this. 🙂
Ishai has been kind enough to release his beta code, so if you need to override the content by query web part, his solutions will give you a flying start. Be aware that is still a beta and needs some more improvement before it can be used in production environments.
