How do I set up filters for the ‘Exhibitors’ tab?

1. Go to ‘Users’ -> ‘User Filters’
2. Click ‘Filters’, then ‘Add Filter’
3. Type the filter’s name in the field provided
4. Click on the blue ‘Assign User Roles’ button, and pick whether you want the filer to apply to exhibitors, sponsor, or both
5. Click the green tick button
6. To make this a sub-filter of another filter, click and drag it underneath the main filter until you see it indent slightly, then release.
