Before I do addins ST program, only one "Addins" Tab. When I added some Ribbonbutton, can be grouped by different "CommandBarname".Now "ST3" in "CommandBarname" becomes multiple different "Addins" Tab.I think ST3 is only one "Addins" Tab, how can I do it?
I'm trying really hard to understand exactly what you're asking but I'm having trouble. Maybe you can take some screenshots to describe what you're wanting to do.
Also, if you haven't looked recently, the latest release of http://solidedgesamples.codeplex.com has a really good .NET RibbonBar addin sample.
