Not sure how you've got it coded now, but you can either hide the textInput or maybe override selectedLabel

I'm so close to having this working. The last problem I'm grappling with is on the initial population of the combo box, everything is displayed as expected - only my graphic (within a canvas). But once an item in the drop-down box is selected, the combo box displays both the new graphic AND [object MyObjectName]. I know I need to do something additional than what I'm doing in the updateDisplayList function but am unsure as to what. ________________________________ Michael J.

The drop down has a custom renderer which shows a label as well as a graphic of the shape. What I'd like to do is display this shape not just in the drop-down menu, but when the combo box list is closed(show the image as the selected item). Righ now, I can only get it to display text. Is this not possible? Suggestions?
