« on: December 10, 2016, 08:32:16 pm »
I click for empty DropDown and I want that empty list does not drop down. Nothing, not needed empty rectangle.

Property   ComboBox1.DroppedDown:=false;   doesn't impacts on behavior of ComboBox

Description:

Indicates whether the drop-down list has appeared.

Setting this property opens or closes the drop-down list.

What widget set (or platform) are you using? You have to add Items in TStrings to a ComboBox to display them.

DropDownCount:=0  shows 1(not 0) items. Why ?
