how do you make a tab on your facebook profile have a bunch of different apps on it?

i saw on my sisters profile that she has a tab that says "boxes" (the tabs on the top of the profle that say wall, info, photos, ect.) and on that page she has a bunch of different apps. she has her heritage, her personality, her honesty box, and a few other things. does anybody know how to do this?

If you add other applications to your profile, there will be a tab made, or if you click on close button, it will ask you to move the current applications to the boxes page.
