How to update blueimp jquery file upload to use Bootstrap 4+

Question

Welcomed dear reader!

It seems Bootstrap 4 does not use the CSS class .in{...} any more.

This influences blueimp jquery file upload in the way that the list of files to be uploaded will not be shown after pressing the Add files button.

Do I do anything wrong? - Or can this class be added to the blueimp jquery file upload framwork/app?...

Best wishes!

Answer 1

Just add this to your stylesheet

.fade.in {
    opacity: 1
}

Answer 2

I may be a little late but I made it work by adding show after fade to the <tr> tags.

<tr class="template-download fade show">

and

<tr class="template-upload fade show">
