Hi

Bug Report: collapse doesn't work in admin vote

class Article(models.Model):
    title = models.CharField(max_length=200)
    content = FroalaField()
    tags = models.ManyToManyField(Tag, related_name="ArticleTags", verbose_name=_("tags"), blank=True)
    seo = models.JSONField()

    def __str__(self):
        return self.title
        
@admin.register(Article)
class ArticleAdmin(admin.ModelAdmin):
    fieldsets = (
        (_('Article Information'), {
            'fields': ('title', 'content', 'tags'),
            "classes": ["collapse"],
        }),
        (_('SEO Information'), {
            'fields': ('seo',),
            "classes": ["collapse"],
        }),
    )
