Describe the bug

Dropdown menu check：

Reproduction

Set the demo config to nav:

export default {
  themeConfig: {
    nav: [
      { text: 'Guide', link: '/guide' },
      {
        text: 'Dropdown Menu',
        items: [
          {
            // Title for the section.
            text: 'Section A Title',
            items: [
              { text: 'Section A Item A', link: '...' },
              { text: 'Section B Item B', link: '...' }
            ]
          }
        ]
      },
      {
        text: 'Dropdown Menu',
        items: [
          {
            // You may also omit the title.
            items: [
              { text: 'Section A Item A', link: '...' },
              { text: 'Section B Item B', link: '...' }
            ]
          }
        ]

[brc-dd]

Items cannot be nested within items.

They can be. Docs are correct. The types are probably wrong.

My solution:

export interface NavItemWithChildren {
  text: string
  items: {
    text?: string
    items: NavItemWithLink[]
  }[]
}
