No idea, what this means:

class MailboxAdmin(ModelAdmin):
list_display = ('localpart', 'localdomainfk', 'type', 'aliastargetaddresses', 'created', 'updated')
fieldsets = [
(None, {
'fields': (('localpart', 'localdomainfk'), 'accountfk', 'lifetime', 'type')
})
]
def fieldset_section(self, title, fields, classes=None) :
if classes is not None :
return (title, {
'fields': fields,
'classes': classes }
)
else :
return (title, {'fields': fields})

def get_fieldsets(self, request, obj=None) :
alias_classes = mailbox_classes = None
if obj :
if obj.type == 'A' :
alias_classes = ('collapse',)
elif obj.type in 'MS':
mailbox_classes = ('collapse',)
fs = self.declared_fieldsets
fs.append(self.fieldset_section('Mailbox',
('aoxuserid', 'quota'), mailbox_classes))
fs.append(self.fieldset_section('Aliases',
('aliastargetaddresses',), alias_classes))
fs.append(self.fieldset_section(None,
('remarks',)))
return fs

That is exactly your code, with the conditionals adjusted a little bit.
1st time after runserver, I get: 'Key 'aoxuserid' not found in Form'

{% for line in fieldset %}
<div class="form-row{% if line.fields|length_is:'1' and line.errors %} errors{% endif %}{% for field in line %}
{% if field.field.name %} field-{{ field.field.name }}{% endif %}{% endfor %}">

Next time, I open this page, it renders all 3 (aliases, mailboxes and remarks) fildsets twice. That means it does not collapse at all.
The number of repetitions of the 3 fieldsets increases each time I display that form.
