Can I create a question with multiple text box answers AND an option to add more if needed?

I want to have a question where the participant is listing something. I've figured out the Javascript to have multiple text boxes in one question (without labels) but I also want participants to have the option to add more boxes (such as a plus sign) if they have more to say. The picture I've attached is sort of what I'd want it to look like. I assume I would need Javascript so would someone also be able to tell me what the Javascript would be?
