I have the following problem. I have two custom fields for date. The start date and end date. How can I set a filter to display results in these two custom fields? E.g. If a given event starts on 10/12/2019 (custom field start date) and ends on 20/12/2019 (custom fields end date) then by selecting the range 8/12/2019 - 15/12/2019 then the event has been displayed and also if the scope is selected 15/12/2019 -25.12.2019.
