Doxygen document structure with python superclass

Question

This is my first question in stack overflow: This is my Python project structure:

superclass1:

1. module

2. class1 and it's modules

3. class2 and it's modules

superclass2:

4. module

5. class2-1 and it's modules

6. class2-2 and it's modules

How can I replace this type of structure in my documentation generated by Doxygen? I'm using doxywidzard and the configuration file associated.
