I am using DayPickerInput and I have it set up like this (Range with 2 day picker inputs). I want to always display overlay and I don't want to hide it. I am aware of showOverlay prop but it only displays overlay during the initial rendering and the overlay can be closed. Once closed it won't be opened by default again. Is it possible to have overlay always displayed using DayPickerInput or I should use DayPicker with my own input fields?
