Selecting cell on the calendar from select box

When I select "277928 İsimsiz" area which is specified with red lines, can we make a selection on the calendar field as in calendar marked with red lines with number 2?

The rectangle, which is drawn in red with number 1, contains the date range and column information.
The rectangle, which is drawn in red with number 2 selected with mouse but I want to select it from the div area (number 1).

Thanks.
