title: How to change combobox selected values display order
body: <p>I would like to change selected records display order in a combobox. The reason is that, as you can see from the screen shot, the combobox list so long therefore employee can't see selected values easily. Are there any method/function to change displayed value sort order based on the selected record index?</p>
