items parameter ignores item order

[pgainullin]

The list ends up being sorted alphabetically by label of the MultiSelectItem(), ignoring both the original order of items and the compareTo function of value.

Ideally there would be a parameter that would determine how items are sorted, or at least the original order is respected.

Generalising this further we could have a list builder that would also allow to show part of the items for larger lists for example.
