Staff / Team members can be added to the “Staff” tab in the admin menu. You can use the default WordPress texteditor or WPBakery Page Builder to build up your single staff page.
If you don’t want or need a single staff page you can only add the Title, Featured Image and Staff Details. To display the summary of these projects you can add the “Staff” page builder element through WPBakery Page Builder on any page.
