Support for inline/fieldsets collapse

There currently isn't support for collapsing inline models. i.e. classes = ['collapse'] results in the objects disappearing entirely.

Collapse has no effect on fieldsets, i.e.

fieldsets = (
        ('General', {
            'fields': ('foo', 'bar',),
            'classes': ('collapse',),
        }),
    )

Which changeform_format are you using within your JAZZMIN_SETTINGS ? the default one horizontal_tabs ? or one of the others ?

on a seperate note, I dont see fieldset classes coming through on all changeforms, so I've got a PR up to address that See https://github.com/farridav/django-jazzmin/pull/375

But id need to understand your use case a little bit more to know if it helps..

Mostly using horizontal_tabs I'll be using collapse in several fieldsets, but primarily right now, looking to collapse some large inline models.

  class VersionInlineAdmin(admin.StackedInline):
      model = Version
      # fieldsets = (
      #     ('General', {
      #         'fields': ('foo', 'bar',),
      #         'classes': ('collapse',),
      #     }),
      # )

Tested this manually by adding:

<button type="button" class="btn btn-tool" data-card-widget="collapse"><i class="fas fa-minus"></i></button> to the "card-header" div, like so:

<div class="card-header">
<button type="button" class="btn btn-tool" data-card-widget="collapse"><i class="fas fa-minus"></i></button>
...</div>

It appears as if the button needs to be added to the card header.

AdminLTE reference

Presumably this needs to be added to the stacked inline template, around line 13, in the <div class="card-header"> element.

I have same observation, Setting 'classes': ('collapse',), in admin fieldsets does nothing. I'm using changeform_format set to single.

similar observations about inlines model, when you set settings classes = ['collapse'], you could observe browser console logs
