i solved it. :slight_smile:

Hello!
I copied the source code ported from cocos2D for iphone (http://brandonreynolds.com/blog/2011/01/09/cocos2d-sliding-menu-grid/), based on the source code on this thread page K pop. I corrected several errors and added a few features (tags for each page)

I am new to this place,
could you please tell me how to integrate this with my HelloWorlsScene.cpp??

I have tried a lot but i keep getting errors!
