Combo box drop down fonts

I got realy confused with changing combo box drop down text size. It is realy frustrating browising through your forum existing topic; they're poorly categorized.

var listFilter = new AW.UI.Combo;
listFilter.setId("listfilterinput");
listFilter.setControlText("Active Items");
listFilter.setItemText(["All Items","Active Items", "Inactive tems"]);
listFilter.getContent("box/text").setAttribute("font-size", "10px");
listFilter.setItemValue(["all","active", "inactive"]);
listFilter.setItemCount(3);
listFilter.onControlTextChanged = function(i){
}
listFilter.refresh();

For the popup list items that should be

listFilter.getItemTemplate().setStyle("font-size", "10px");
