Thanks for fast reply and update.
It;s much better now but still have one issue left as I can see so far.
When I just changed categories and reset everything works as expected. Categories set to default and search results reloaded and it’s all good.
But when I have entered search keyword (e.g., 1.09.2020.) and get good search results for this
and I hit reset button. Search box is reset to empty but I still have that search results shown from last search. I have to hit enter or search button to get valid search results for current search form.
I need to get valid search results instant on reset button (just like this form works when only categories have been changed.)
