Hi Fabio, to identify each fieldset with a name to handle its state, one option is to add a data attribute to each fieldset with the name suggested in issue #173: {app_name}-{model_name}-{fieldset_name}. To achieve this, I need to include a copy of templates/admin/includes/fieldset.html to override it. Is this a good idea? I'm thinking if this could be a problem if Django changes this file in future releases?

If it's possible to override fieldset.html file, then in static/admin/js/collapse.js I could get and set the state of each rendered fieldset.

What do you think?

Hi @luciano-im,
I understand the problem, an alternative could be to add the data attribute dynamically using js without overriding the default admin template. What do you think about this solution and its pro and cons?

Actually there are already some admin templates that gets overridden and frankly I'm a bit worried about potential problems in future releases, but once #301 will be done, this will be no more a big problem.

I understand clearly. Let me see if I can find a javascript solution so that the default template doesn't need to be overridden.
