Python Wagtail-为特定StreamField设置内容面板

我希望我的用户能够在wagtail freeform编辑器中定义列式布局

为此，我创建了一个流块，如下所示：

class ColumnSplitBlock(blocks.StreamBlock):
    class Meta:
        template = "common/column_split_block.html"
        icon = "grip"
        label = _("Columns")
        min_num = 1
        max_num = 2

然后我将其插入页面的Streamfield：

class NewsDetailPage(Page):
    template = "news/news_detail_page.html"
    parent_page_types = ['news.NewsListPage']

    content = StreamField([
        ("rich_text", blocks.RichTextBlock()),
        ("image", blocks.ImageBlock()),
        ("column_split", blocks.ColumnSplitBlock(
            [
                ("rich_text", blocks.RichTextBlock()),
                ("image", ImageChooserBlock()),
            ]
        )),
    ], verbose_name=_("Content"))

    content_panels = Page.content_panels + [
        StreamFieldPanel("content"),
    ]

但是，我想自定义StreamBlock中ColumnSplitBlock的显示

特别是我想用它来创建管理编辑器中提到的专栏布局。这可能吗
