Floating Group - Not showing other elements in element inspector

m trying to make a vertical menu, with displaying groups to the right, ive searched online high and low but nothing specific to help. I used someone else template on the marketplace to try and understand how they did it, because they seem to get it working, but when I go and do the exact same thing, it doesnt work. Im trying to set state in my floating group, but it isnt allowing me to view other elements in my element inspector. I dont know if this is an issue as to why my groups dont show or what.

ive tried so many things to try to fix this, but im not getting anything to work. Can you assist me with this?

ive uploaded what I have, maybe it helps.
