InlineModelAdmin Options

With Grappelli, you get some additional attributes for defining your InlineModelAdmin.

collapse-open, collapse-closed

You have two options for displaying inline-groups. With "collapse-open", the inline-group is collapsible and open by default. With "collapse-closed", the inline-group is collapsible but closed by default. Without using a class, the inline-group won´t be collapsible.

class NavigationItemInline(admin.StackedInline):
    
    classes = ('collapse-open',)
    ...

allow_add

With using allow_add, you´ll get the "+"-Button for Inlines.

class NavigationItemInline(admin.StackedInline):
    
    classes = ('collapse-open',)
    allow_add = True
    ...
