I want to use Blueimp File upload plugin to upload single audio file but by setting
still breaks my layout by allowing other files to show up.
This is how it's supposed to look like.
I don't want the second file to show up.
Solution in mind
I believe I can solve this by adding an before_add event to the file upload so I can clear up the current selected file and add a new one. That means they'll never appear multiple files.
I don't know how to add an event and especially the one before add.
