On a form in my application I have a combobox that allows the user to select one or more functions to be used in the task at hand.
I have used a Combobox that shows a list of checkboxes in its dropdown
So I currently display all selected items comma-separated in the combobox area. If multiple functions are chosen, this text gets too long to be displayed so I chose to cut it off with "..." like this:
My questions is: Is that the ideal way to abbreviate the text in the combobox? I could also think of, instead, showing the number of selected items like "3 functions", which I guess gives more information that the abbreviated list. What would be the best choice?
