but no select field to fire filter options:
on the other hand, if enable this filters to simple module in app folder,
(except notification) appears dropdown fields with filter options:
popover = shows dropdown arrow in search box
collapse = shows collapsible area above list box
no value = shows next to search box
I didn't noticed that triangle and after changing the value of "advanced_search" to false it worked!
