Use the dropdown lists to filter the resources. The result list gets updated as soon as you
select a filter option.
Your filter choice also reduces the available options in the other filter options to the values
matching the entries in the result list.
Example: if you select 'Imagineer' from the 'Role' filter the 'Person' filter will get updated to
contain only persons which are imagineers.
