At the moment, in order to see the suggestion list display you need to enter at least one-character prefix. It would be useful to have an API property that would allow passing an integer value to configure the length which would make the list appear. For example, if you set the value to 3, you would get no suggestions until you entered a three-character prefix. On the other hand, if the value was set to 0, a click on the selector would be enough to see all of them.
