Hi, 
 
I was wondering if there's a way to upload multiple files to Maropost's default contact form. 
 
I've tried adding the multiple attribute to the file input field but that didn't work.
 
I see that all the files get uploaded to the form properly but the form either is not processed (if the file name is inp-files) or is sent without any images (if the file name is inp-files[]).
 
I also changed the Form upload field in the contact form backend to files.
