[Feature Request] Add transition for options list

[vencho-mdp]

Problem description: When having a large amount of dynamic options is quite difficult for the user to differ which ones have been deleted / added. Transitions could address this problem, why showing this process progressively.

Suggested solution: I think that if we had access to the wraper of the v-for (maybe through a slot or something else) it could be done quite easily. Another one could be to have a transitionName which defaults to null (no transition),
