"MenuItemComponent" Component - No propTypes defined!

[ChenJiaWe]

When I want to use child Components in a Conmponent,I want to show the propTypes of the child Conponents.

Thats what I see in Storybook:

This is my code：

export default {
    title: "Menu Compoent",
    compoent: Menu,
    decorators: [withInfo],
    parameters: {
        info: {
            inline: true,
        }
    }
} as Meta;

export const defalutMenu: Story<MenuProps> = () => (
    <div>
        <Menu defaultIndex="0" onSelect={action("selected")} >
            <MenuItem >
                cool link
  </MenuItem >
            <MenuItem >
                cool link 2
  </MenuItem>
            <MenuItem >
                cool link 3
  </MenuItem >
        </Menu>
    </div>
);
defalutMenu.storyName = "Menu";

What should I do ? Is my code wrong?
