How could I categorize group?

Like in this community, when I click on "Groups" on the almost top tab I could see "Featured Groups", "All Groups", "Support",...,"Plugins". But in my own elgg, there are only "Newest", "Popular", and "Lasted Discussion". I would like my elgg to be able to caterize group like the communicty here. How could I do it?

Thanks in advance...

P.T.
