I can't look at the code right now, but there was something weird about the code - as far as I could tell, the static VI had the subpanels (the Controls[] property showed an array on a probe), but when I placed them at a certain point on the FP and told them to be visible, I still couldn't see or select them. I don't know why that happened.
In any case, you should go back to the original example to see how this works - it works exactly by having "enough" subpanels and only showing some of them. In practice this isn't a real problem because creating enough subpanels (64, 128, whatever) can be done in roughly the same amount of time it took me to type this paragraph by ctrl-dragging groups of them. This only becomes an issue if you want to have additional stuff going on (such as having a label near each plugin or something similar), but that can also be handled.
Like I said in the other thread, it's also possible to create an unlimited display by creating a limited number of subpanels and then rolling them and swapping out the VIs displayed in them, but that code is considerably more complicated than simply duplicating the subpanels.
