New to KeystoneJS, how do you limit file extension upload?

[yasir-fayrooz]

I have a Field of type File and it uses an appropriate LocalFileAdapter to store my files statically. I want to be able to limit my file extension types to images only but i cannot seem to do so in KeystoneJS 5. The current upload button shows all file extension types...Any ideas? I'm stumped right now. I know it has something to do with Mimetypes

I think this is not possible at the moment. It would require that File field type could define the accepted file types so that the information could be used in <input> element, https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/accept#limiting_accepted_file_types
