How to make dynamic interfaces with VSTGUI?

Hi.
I partially understood how to deal with VSTGUI to create static interfaces in UI editor.
But how to make dynamic interfaces?
First that I need is to add/remove segments in CSegmentButton during execution.
Next is dynamic mod matrix:
ScrollView->RowView->ViewCotnainer
ViewCotnainer contain mod source and destination selector (OptionMenu) and slider for mod depth.
So I want add/remove single ViewCotnainer from RowView when button pressed event in data.inputParameterChanges catched.
VSTGUI documentation is so poor and didn't give any info about.

Anyone? Any starting point?
