I having trouble with a simple question : How to have some \"disabled\" field in a dropdown menu generated via a modelForm and choiceFied in the django Framework ?
Are you trying to create a menu in which the list items are separated into categories, and you don't want the categories themselves to be selectable?
If so, you can achieve this by having your template render the field using tags, e.g.
Elt 1 Elt 2 Elt 3 Elt 4 Elt 5
