如何导入子类别CSV？

Question

我想用它导致多个catgories导入CSV。有父类别和多类别。假设在下面的考试中我需要保存dl（Subcat）然后应该保存在default(cat) -> manza(Subcat) ->manza 20 (Subcat)->manca xl(Subcat) ->dl(Subcat)

下

就像我的代码

一样

parent cat  child cat-1  child cat-2  child cat-3 child cat-4    name 
deafult      manza        manza 20     manca xl   dl              dl

means:

name   path
dl     deafult/manza/manza 20/manca-xl/dl
