I'm not sure what you meant by import lists into dropdown, could you give us more details of it?
If you have a very long list of items, then I would suggest using our widgets instead, please check this page: http://widgets.jotform.com/category/multiple_entries.
I hope that helps. Do let us know if you need more information on this.
