The mailing list for listmasters using Sympa

[address@concealed]

Hi all,

I have finished Sympa 3.4.4.3 and now it is working very well :) , but i have 
question.
Now when i add a a list , the wizard asks me in which category shall i put 
this list in, (say for example i put it under the category of News and Media) 
now i need to make the sub-categories are visible to users (i.e. The main 
Category and under it the sub-category)
like this

* News and Media
    - List-1
    - List-2

* Education
    - List-1
    - List-2
 and so on ...

So can anyone help me to do this ?????
