I use the Latex package mdframed to define "environments" containing headlines and text. However, I would like to add some personal notes which should not (!) be displayed, if a boolean variable is set to false. How can I achieve that?

This is how I did it, finally:

%% Define a boolean variable
\DisplayToDostrue   % display the toDo-environment 
%\DisplayToDosfalse % uncomment to hide the toDo-environment 

% This will be used below to define an empty environment via \NewEnviron

% Depending on the boolean variable, I define the environment:
  % define proper environment
  % def. empty environment
