It would look like a normal drop-down with out any info in it. The only thing that is hard coded is the data(names of your saved searches). The style(what it looks like) is not hard coded and there for you to see/change. The placement and look is not hard coded.
Incase you wanted the actull code and couldn't find it...
Code:
<Dropdownbox BackgroundOpacity="1.000" DataSource="FilterSource" Location="390,2" MaximumSize="16384,32" MinimumSize="50,32" Name="SearchFilter" RowTemplate="/CommonElements.Dropdown.data.dropdown_template" ScrollExtent="176,32" SelectedItemIndex="12" Size="176,32" Style="/CommonElements.Dropdown.data.style" />
