Current behavior
AutoComplete has an appendTo property that allows you to move what element the ui-autocomplete-panel will be attached to. However, it is much more difficult to style the component once you've done this because the panel is now no longer affected by styleClass or inputStyleClass.

Expected behavior
It would be very helpful to have an autoCompleteClass or something similar that allows the user to attach a CSS class to the ui-autocomplete-panel.

What is the motivation / use case for changing the behavior?
Better styling support for the AutoComplete when using appendTo.
