Hi @iamlasse
Thank you for using Filter Everything.
In general it is possible with PRO version because you can use option “Hide empty Filters” and if a filter has no intersections with other filters it will be hidden automatically. And also you can use feature “Parent filter” that hides a filter until his parent is selected. BTW, now is Cyber Sale Week and you can buy PRO with discount.
But also you can achieve the same with Free version and using hooks. For example you can create empty-filter.php
template that does not display anything and use hook ‘wpc_view_include_filename’ that handles what template will be included for current filter. Also you can use function flrt_selected_filter_terms();
to detect what filter terms were selected.
I hope this will be useful for you.
