How to append input files instead of replacing when the user picks the files again?

I would like to allow the user to make file selection multiple times. I will show the selected file names in a table below and would like to add the newly selected file to the table.

There is a EditModelFormMultipleView view in the example project that does this.

django-file-form/testproject/django_file_form_example/views.py

Line 232 in dbe8090

    
           class EditModelFormMultipleView(FileModelFormMultipleMixin, generic.UpdateView):

This example works with a ModelForm, but it should also be possible with a normal form. The trick is to override get_initial.

Also, is there a way to allow the user to remove the files?
Kinda like this:
