I think nconfig is a better fit for your system.


In my understanding, the concept of menuconfig
is to use a similar appearance to the 'dialog' tool
although we have largely modified the code.

You missed to adjust dialog_textbox().


(1) Run 'make menuconfig'
(2) Press < Help > button to show help message
(3) Press < Exit > button to get back


When you do (2) and (3), please make sure
the size of the grey window is not changed.

This is how the current menuconfig works.



I want to leave the blue frame.
My personal preference is

  height -= 3;
  width -= 2;
