Hi there!

You should import custom sub-menu component (see docs)
Screenshot: https://i.gyazo.com/bc8d07bb333546164dff9ca8a779e858.png

But i have already input antd globally,Is there still have the necessity to input again?

@xiayuying <a-sub-menu /> not <sub-menu/>

Hi,

I have a similar issue, I used the fully imported Antd but I want to switch to importing components one by one, if I import "Menu", I have the same "Cannot read property 'propsData' of undefined when I replace <a-menu ..> with <Menu ..>

@mgnrfk Have you found any solution?

This appears to be a design problem in SubPopupMenu::render() around line 393, where the code makes an assumption that child nodes are antd menu items. That prevents using other components within such as OP's example, or portals/slots for dynamic menus, and so on. For example, you will get the error doing code below if the slot contains anything other than antd items (such as wrappers):

<a-menu> <slot name="menu-items"></slot> </a-menu>

但是我已经antd在全球范围内输入了，是否仍然需要再次输入？
不需要了

When I wanted to use ant-design-vue dropdown menu plugin, I was getting such kind of error. My components registrations was like this;

components: {
  'a-menu': Menu,
  'a-menu-item': Menu.Item,
  'a-dropdown': Dropdown,
}

Then I removed the 'a-menu-item' line, the error disappeared

components: {
  'a-menu': Menu,
  'a-dropdown': Dropdown,
}

maybe it could be help

same issue

@xiayuying <a-sub-menu /> not <sub-menu/>

加了还是有问题
