I am using a DropDownList with dynamic items that are grouped.
When opening the dropdown without items in the datasource the fixed group header is displayed empty.
When removing the last item from the datasource after the DropDown has already been opened, the first group header is still displayed when opening the dropdown.
I would expect the group header to never be displayed if there is no data.
