I have not got a response back from the Django admins regarding my blocked first response to your post. So I’m posting over again.
I’m not using forms.RadioSelect for my multi select widgets. I’m using forms.CheckboxSelectMultiple with models.ManyToManyField(SubwayVeggie). I assume you mean tuples when you say “two column” select. I’m using those for other fields and they work fine for small lists. But I need to use the ManyToMay for larger lists and be able to maintain the list in the admin section. However I can’t find any documentation that explains what I’m looking to do.
-
Show the multiple selections in the subwayOrder. In the veggies field see a comma separated string of the values selected in the veggies column.
-
Show the values in the admin section using radio buttons rather than the default list.
-
Have the values selected be posted with the rest of the selections. I can do this with single selections just not with multiple.
