WooCommerce在产品页面上显示分类类别和子类别

Question

我试图在WooCommerce产品页面上显示一种名为“ product_fit”的自定义分类法，其结构如下：

Car maker (as main parent term)
- Car model (as child term of Car maker)
-- Production year (as child term of Car model)

如何在产品页面上显示它？ 我没有找到任何示例代码。

我尝试在产品页面上填写此表格：

Ford:
- Focus (2007,2008,2009)
- Mondeo (2009,2010)
Opel:
- Astra (2010,2011)
- Corsa (2009)
