I have a hard time duplicating the suggestionBox behavior in Richfaces demo, where the box won't pop up if there is no matching suggestion. In my case, the box always pops up with a fixed size. When there is no suggestion, or fewer suggestions than filling the box, the blank area is of a background-color that I can control with class ".suggestionBoxSelected". How do I (1) avoid the pop up when there is no suggestion? (2) control the height of the box so that there is no blank rows beyond the suggestions (up to a maximum above which a scroll bar will appear)?
Thanks for help.
