There are default friend lists in Facebook such as Family and Close Friends. They’re listed in the Friends section in the left navigation bar. You can add more at any time. Here’s how!
1. Left bar: FRIENDS > MORE
2. + Create List
3. Add a List Name.
5. Add Friends
6. Select friends to add and click Finish.
Your list shows up in the left navigation bar. Select it at any time to see posts from the friends on that list. If you don’t see some for any one person, it’s because they may not have posted anything in a while.
