Question

我需要在顶级菜单上仅显示第一级别类别及其产品，以取代Magento的默认顶级菜单。

例如，类别和产品应显示为：

Category1
    Product name1
    Product name2
    Product name3
    Product name4
Category2
    Product name1
    Product name2
    Product name3
    Product name4

在块类中生成的菜单html结构，它将直接在phtml中使用。

由于在商店中仅使用第一级别类别，因此不需要类别树结构。

任何人都有这个任务的想法吗？

您需要重写导航和顶级菜单Magento块。
