DatePicker with no default dates set

Hi All

I using the DatePickerRange component but I don’t want to show any dates till the user clicks and selects his or her start or end date. If I don’t provide a start and end date to a picker, it just doesn’t work .

my code below

html.Div([
                html.H5("Filter by date range:",className="one columns"),
                dcc.DatePickerRange(
                    id=self.title+'my-date-picker-range',
                    display_format='DD-MM-YYYY',

                ),
            ],id=self.title+"output-container-date-picker-range",style={"marginTop":5}),

The way it is now, this is what i get datepicker

but when the user clicks the start date there is no drop down? what am I doing wrong?

thanks
Andreas
