CSS issue on combo box.

please help me to solve these CSS issues.

Figure 1 :
clicking in combo, by default it is opening downward but if it is the last row in the dhtmlx div then it should open upward.

Figure 2 :
If the combo is open and the user scroll the scroll bar then the combo is not moving…
i want to close it , when user scroll.

Same things is happening with text area.
