问题
Is there any way, I can color a tag(with different colors) on on-tag-adding event, for a tag entered by user which is not a part of suggestion list? i.e. as a warning to user that he is going to add unknown tag(in red?)
also, How Can I make input box re-sizable vertically as we add more and more tags?
