Custom form in the Admin: how to make it look the same as Django's Admin forms?

kevinrenskers I had the same issue.
I have managed to resolve it by doing this:

fieldsets = ((None, {"fields": ["user_1", "user_2"]}),)
context = dict(
    self.admin_site.each_context(request),
    opts=self.model._meta,
    title="Copy Permissions",
    form=helpers.AdminForm(
        CopyPermissionsForm(),
        list(fieldsets),
        {},
    )
)

I also have this in my html file.

{% block extrastyle %}{{ block.super }}<link rel="stylesheet" href="{% static "admin/css/forms.css" %}">{% endblock %}
