At the time of selecting tags(data fetched from database for that particular AutoComplete) you need to manage validation for the such kind of the requirement which will be handled through the one type of the tags array or data-model. So when you select any of the tag then its checks inside the array or data-model if entered tag is not exist inside the array or data-model then it should fire the validation.
