UI - Create custum UI from menu bar


Hi at all,

I’m trying to create a window to make all Maya menus available, so I can keep it open in the second monitor, without separating the menus each time. I use many and a shelf is not enough for me, I would prefer to have them all clearly visible. The attached image can give you an idea of what I am trying to implement.
What I would like to do for facilitate and speed up the work is to use the code with which menus were written and insert into maya layout.
Can you tell me if it’s possible and if so where to find that code?
Thanks in advance
