I am new to Django and Python programming and I have looking in circles to solve this problem I have. I wrote following codes...whenever the below codes were executed, the inline filter is always default as 'close'. How can I default to 'open' or 'show' instead of default 'close'? Thank you.
class ArInvoiceSimpleInlineForeign(admin.TabularInline):
model = ArInvoice
extra = 2
classes = ('collapse open',)
inline_classes = ('collapse open',)
