We use a DatePicker component in our project. Primefes Version 10.
<p:datePicker id="range" selectionMode="range" showTime="true" />
Period selection works great:
The selected period will be deleted when I change the time.
Is it possible to use Date Range Picker with a Time?
Currently that is not available but has been requested on GitHub. I suggest you go upvote the issue there.
