Re: Is there a orded ModelMultipleChoiceField ?

DId you try to ordered your queryset ?

... to discover the order the user made the choices, if I understand
what you want, you have to use some way (ajax), to persist the order
somewhere.. and then populate your choices filed following the order
persisted.

Did that helps?
