How to close the ComboBox list on mouseExit?

Hi all, as the title says i would like that the ComboBox list would close as soon as i move the mouse out of the list without the need to click, so far playing with mouseExit i can catch only 1 parent and 1 child that are the little 2 arrows on the right of the ComboBox and the Label with the text of the selected item, but no way to catch the Popup menu with the list to close it when the mouse move out, can someone drive me in the right direction? thx all as always :slight_smile:
