Manage App People Categories Page Explained

If you have created any People Category under the "General" tab, you can specify the name of each custom People category on "Manage Application" > "People" > "Categories" page. These category names become the drop down options that people can choose from in the People Index page. 

For example, if your custom category is "team", you will add "team A", "Team B", "Team C" here.  People will be able to select the team they belong to in their profile.

You can see all the categories created. You can edit or delete the category by clicking on the drop down arrow next to the category.
