It's from 9.3.0. The Date Time Picker Widget Height can't be reduced.
On the Mashup, the Date Time Picker widget is Occupying more space than the widget that is present in 8.3.4
In 9.3.4, also this issue still exists, placing the DateTimePicker widget.
Can someone Help me to reduce the Height of this? Reducing the Height from style properties or custom CSS will not because it cuts off the Container of the widget
