Not tested myself, but have you tried the normal fieldsets = () in a
standard admin.StackedInline class?
Found this via a quick Goog search:
http://www.softwarematrix.cn/blog/django/add-fieldsets-with-admin-stackedinline
Seems like that should work... I normally don't used the "Stacked"
look for my inlines, so hopefully I don't send you down the wrong
path.
MetaModelAdmin.fieldsets[2][1]['fields']' refers to field 'type' that is missing from the formafter removing the specific field and only leave it in the fieldsets of the Inline, everything is working fine
Have a great day!
