We're trying to figure out how we can make it easier for very inexperienced users to add files (not images) to a specific wiki page. We're considering adding specific files automatically based on categories. Now, by default UploadWizard shows a category field with autocomplete. While that looks really nice, it requires the user to actually know the category name, or at least the first character(s). Is there a configuration option to either autocomplete all possible categories once the field is clicked, or to replace the field outright with a simple dropdown menu. Of course we can imagine this is not the most common use case, but it would be practical for us if one of those options happened to be available.
