clion Code Folding?

Hey

How can I enable code folding in clion ?  The little + next to loop/while/etc?

Also in cmake..

Say I have

set(someSrc
        path/path/aa.cpp
        path/path/aa.h
        path/path/bb.cpp
        path/path/bb.h
        )

I'd like to fold that in to 1 line  

Same goes for

vector<int> ve = {

1,2

2,3

4,5

};

etc etc etc?
