How would you go about creating a database that has endless groups unlimited levels deep? Ie: Your business has 100 teams and some teams have subteams.. and those subteams can have unlimited sub teams as well.

I have it set up where my database has a subcat field for the parent group in which it exists. I have that part all taken care of.<p. The question then is, when I print out all groups, how do I keep all the groups and subgroups together? For example 

id   gname      subgroup
1    red team      0
2    orange team   0
3    black team    0
4    girl team     2
5    guy team      2
6    heavy weights 5

and have the result be 
red team
orange team
> girl team
> guy team
>> heavyweights
black team

The trick is, I have to be able to advance-sort these teams by many different fields dynamically (id asc, name desc, size desc...) and I'm completely lost on how to go about this.

This is MySQL if anyone needs to know what database I'm trying to use.
