Drop down list as answer options

Hello,
Your poll widget is great, I love using it (easy to install and handle).

I need to create polls with a very long list of answers (50 to 300, depending on the polls) and I would like the respondent to be able to choose his answer via a drop down list. The content of the list would be clearly stated by me (no new answer given by the respondent).
Is that possible and how ?

It would be even better is if the list could be narrowed as the letters are typed (if the first letter written is a “A”, only the answers begging with an “A” appear in the drop down list)

Do you have any idea how I can do that ?

Thanks for your answer.
