Doxygen - grouping in navindex

See more:

C++

Hi guys,

Is there a way how to group entries in the navigation index of HTML output generated by Doxygen?

At the moment the structure looks like:

module
|__macro1
|__macro2
|__function1
|__function2
|__function3
|__varible1

and I would like to group these items like:

module
|_macros
| |__macro1
| |__macro2
|
|_functions
| |__function1
| |__function2
| |__function3
|
|_variables

etc.

Functions and variables are not a big problem, but defines and enums are making quite a mess in the navigation index and grouping them would be nice. :-)

Thank for any advices!
