[patch] ChoiceField should allow for nested choice sets

Description

It would be really useful for the ChoiceField choices parameter to allow grouped sets of chioces (much like the Admin class allows for grouped fields). That way, the default widget could output HTML which encloses groups of OPTION tags within OPTGROUP tags.

Sure, that'd be a pretty good improvement. Please implement this as GroupedChoiceField and put it in django/newforms/extras, along with a GroupedChoiceWidget.

Do you really need a new GroupedChoiceField for this? For validation purposes, it's entirely identical (the grouping doesn't affect the HTML value at all). All you need is a way to provide grouping for rendering. As ChoiceField uses Select as a default widget, this could be done by addding a GroupedSelect that handles the grouping (either as a mapping of group-label => input-value or the other way around).

I'll work on a patch for this... it seems like unnecessary duplication to have a separate Field.

How is this different from #4412? At the moment, we are favouring committing #4412 once newforms-admin has merged, so unless this adds any significantly extra functionality, let's close this as a duplicate of #4412.

Agreed - this is a dupe of #4412, which has a better integrated and more complete implementation (including docs and tests).
