Where to Find

I want to add a submenu for a particular Group page. Has anyone applied this. Where? I do not want it to be for every group just one.

I think we will need a photo of what your trying to do. I can tell you that there is most likely no built in way to do it in dolphin. Dolphin does not have a system in-place that will allow you to build custom menus for a specific page and stick it at a specific location. So i can pretty much assure you that you will have to build it by hand.
