Pro: conditional fields and file uploads

Conditional fields

Under a field choose Show only when a Choice or Checkboxes field has the answer you write. The field appears only then; while hidden it is not required and is not saved. Without JavaScript all fields are shown and the rule is applied when the form arrives.

File uploads

Add a File upload field, write the allowed types (among pdf, images, office documents, txt, csv and zip) and the maximum size. Files are checked by their content, kept outside the media library in a closed folder, and can be downloaded only from the entry in the dashboard. Deleting the entry deletes its files.
