Django ModelAdmin Fieldset within fieldset

What I've been asked create is an admin page with the following layout:

and so on.

I can create the fieldsets with ModelAdmin.fieldsets obviously, but its the inner grouping or "Sections" that I'm having difficulty with. The fields to display all belong to the same model, so I can't achieve this with Inlines (or at least I believe I can't).

I'm pretty sure the only way to achieve what I want is to create a custom template and to by pass Django's default loveliness but I'd ideally like to extend the Django Admin because this Fieldset -> Section -> fields layout will be required for several models and I don't want to have to manually generate forms & templates for each model, if I can help it.

Could anyone point me in the right direction to achieve the above layout?

Thanks

It looks like Django still doesn't support nested fieldsets (April 2022).

Instead, I had to go through and organize my fieldsets into tuples

('Water Conveyance', {
    'classes': ('collapse',),
    'fields': (('spillway_gate', 'bypass_valve'), ('trash_exclusion', 'intake_gate', 'intake_passage', 'shutoff_valve'), ('cone', 'isolation'))
}),

And then set verbose_name on all my field definitions

spillway_gate = models.CharField(max_length=25, choices=Key.choices, default=Key.default, verbose_name="Bypass - Spillway Gate")
bypass_valve = models.CharField(max_length=25, choices=Key.choices, default=Key.default, verbose_name="Bypass - Bypass Valve")

Not as pretty, but it works

If you are trying to create a page something like this :

enter image description here

Then you can add following to your admin file :

from django.contrib import admin

class FlatPageAdmin(admin.ModelAdmin):
    fieldsets = (
        (None, {
            'fields': ('url', 'title', 'content', 'sites')
        }),
        ('Advanced options', {
            'classes': ('collapse',),
            'fields': ('registration_required', 'template_name'),
        }),
    )

And for more details you can check this page

Unfortunately you're out of luck, the Django admin does not support nested fieldsets and has no way to output other structural tags, except by customising the templates.

You can have a look at:
http://django-betterforms.readthedocs.org/en/latest/basics.html

It supports nested fieldsets, so this code will help you when you are customising your admin templates.
