Ok, in openbox this is configured with the rc.xml file. Right now you are probably just using the default config which should be in /etc/xdg/openbox/rc.xml. Copy that file to ~/.config/openbox/
mkdir -p ~/.config/openbox
cp /etc/xdg/openbox/rc.xml /.config/openbox/
Now open that file in your favourite text editor. Eg
Look for a line that has:
Each of the letters N, L, I, M, and C represent the different items in the title bar of your windows.
The meanings are:
N: window icon
L: window label (AKA title).
S: shade (roll up/down)
D: omnipresent (on all desktops).
Simply edit that line to represent the layout you want.
I guess you'll have to restart openbox to see the changes
