i am reframing this question since there may be an easier way to do this. https://www.htmlelements.com/demos/combobox/multiple-selection/
if you select both “Coffee Milk” and “Liquor Coffee”, close the window, then click either of the selections displayed, then the drop-down neatly opens and also “scrolls” to the item just selected, so either “Coffee Milk” or “Liquor Coffee” will display, depending on which one you clicked.
is there some way i can determine which displayed selection was clicked? perhaps a callback? i notice that using the “open” event that examing the “event” variable does not appear to contain whatever option was selected unless i somehow missed it.
i apologize for all these nagging questions!
