Feature Request: Sidebar Nav Links

[ulivz]

Motivation

The top navbar of a complex website may be extremely complicated, this results in insufficient space for the top navbar, so we want to introduce an sidebar-embedded navbar, which can help us complete the "overall switching" ability in the Sidebar.

Basic Example

Introduce sidebarNav config:

    sidebarNav: [
      {
        when: ["/guide/"],
        items: [
          { text: "Guide", link: "/guide/getting-started.html" },
          { text: "Migration", link: "/guide/migration.html" },
        ],
      },
    ],

Which will help us render:
