Yes, there is a way to organize Facebook groups. You can use the Groups feature on Facebook to create and manage groups. With groups, you can add people who are in your networks or friends lists, as well as people who are not in your networks or friends lists. You can also create sub-groups within groups. To do this, go to the group's page and click on the Create a Group button. Then, enter the name of the group, select the privacy settings (public, closed or secret), and add members. Once you have created a group, you can add administrators, moderators and other members.
