Wide fieldset fields are hidden.

[James Gillard]

I've traced a change in how one of our fieldsets that contains 3 wide text inputs displays in the admin. The form fields are overflowing the edge of the page. In the 4.2.8-narrow screenshot, the 3rd is initially completely hidden from view. The UI cannot be scrolled but can be tabbed through. Re-adding this removed line of CSS fixes it for me: ​https://github.com/django/django/commit/bd0ea8c2ba9943ed245771265f55645dc3bfeae8#diff-ec6643f5575f7b320d2f0f6b342a6ff8d3d5b29e305e6d3b45ca115774012f99L27

This was working on 4.2.7, breaks on 4.2.8, and I've tested main also and see the same visual change. I don't understand the full history of this change hence I'm not suggesting a fix.

Hello James, thank you for your report. Could you please try with the latest stable release, 5.0 and let us know how that goes?

[James Gillard]

Hi Natalia, the same issue exists on 5.0.0.

[Natalia Bidart]

Thank you James! Could you please provide minimal models.py and admin.py to reproduce the issue?

[James Gillard]

Here's a zip containing a minimal reproduction, and just the models.py and admin.py files below. The issue is visible with only 2 fields, but I've included 3 as that was what my setup has.

class Foo(models.Model):
    a = models.CharField(max_length=200)
    b = models.CharField(max_length=200)
    c = models.CharField(max_length=200)

@admin.register(Foo)
class FooAdmin(admin.ModelAdmin):
    fieldsets = (
        (
            None,
            {
                "fields": (("a", "b", "c"),),
            },
        ),
    )
