I have tried several ways but both staff groups keep showing up. Please tell me how to separate the staff groups? How to show the staff separately? It worked before now it is not working at all. Please help.
Looks like that page is using the staff page template. That’s the way to go if you only need one simple list of everyone. Since you’re wanting to break the list up into groups, you’ll want to skip using pages and instead just add your staff groups directly to your navigation menu. That will give you a “page” (really a dynamic archive) for each group.
If you don’t see staff groups in your navigation menu screen, click the “screen options” tab in the top right hand corner and make sure the box next to staff groups is checked.
If you get a not found error, go to settings in your WordPrss dashboard and click on permalinks. You don’t have to change them, but scroll to the bottom and save the settings. That fixes most not found errors for items like staff groups.
