how to set up a PDF submission Poll

Trying to find where I can do this? "Polls with file attachment per option. Upload your pdf, zip, docx, xlsx, pptx, txt files."

You could take a look at the PollUnit type Voting. If you choose »Image / File« as the option type, participants can upload PDFs and vote on them.

If this does not seem to fit your use case, please describe your project and workflow in a bit more detail so we can recommend the best setup for you.

Thank you!
