This is something we've wanted for a while, but we've never had tome to do it. You're welcome to submit a pull request. I'd be happy to review it.

okay 👍 I'll take a look when I get the chance

do you know if the problem more complicated than adding the word "multiple" to #file-input?

Awesome, thanks!

It's been a while since I've taken a look at it, so I'm not sure. I think the reason we didn't implement this is its more complicated than that. Take a look at the callback on the front end which runs once a file is selected, and then follow the code from there.

The tricky part is deciding what to do if some but not all of the files submit correctly. For example, some of them are the wrong file type, some of them are too big, some fail to upload because of network issues, and some succeed. Well probably want to display success / failure next to each file, or just an error message at the top for each file.

If you could look into it and let me know what you think, that would be awesome!

My advice is to start building just getting multi upload to work, then adding error handling after.
