Menu
Menus allow you to describe the site navigation structure in a simple declarative way. Menus come in two steps:
- Defining a menu.mdfile that contains the menu structure for the directory it's in.
- Using the useContent()function to retrieve the menu structure in a template for rendering. Read more here
File Structure
First layout files as follows:
src/
└── routes/
    └── some/
        ├── menu.md
        ├── layout.tsx
        └── path/
            └── index.tsx  # https://example.com/some/path
Navigating to https://example.com/some/path activates:
- src/routes/some/path/index.tsx: This component will be used for rendering the page content.
- src/routes/some/layout.tsx: This layout will be used to provide content around the- src/routes/some/path/index.tsx. Internally the layout can use- src/routes/some/menu.mdto render the menus.
- src/routes/some/menu.md: This file will be used to declare the menu structure which will be rendered by- src/routes/some/layout.tsx.
Declaring Menu Structure
Use menu.md to declare the menu structure.
- Use the headings (#,##, etc..) to define menu depth
- Use the bulleted list (-) to define menu items.
<!-- File: src/routes/some/menu.md -->

Retrieving Menu Structure
At runtime, any component can retrieve the menu with useContent() hook. The type returned is ContentMenu.
The example above will return:
{
  text: "Docs",
  items: [
    {
      text: "Getting Started",
      items: [
        {
          text: "Introduction",
          href: "/docs/introduction"
        }
      ],
    },
    {
      text: "Components",
      items: [
        {
          text: "Basics",
          href: "/docs/components/basics"
        }
      ],
    },
  ],
}
Using ContentMenu in a layout
While useContent() can be invoked from any component that is part of the current route. It is typically used in a layout component (or a component used by layout) to render the menu. An example usage is shown here:
export default component$(() => {
  const { menu } = useContent();
  const { pathname } = useLocation();
  return (
    <div class="menu">
      {menu
        ? menu.items?.map((item) => (
            <>
              <h5>{item.text}</h5>
              <ul>
                {item.items?.map((item) => (
                  <li>
                    <a
                      href={item.href}
                      class={{
                        'is-active': pathname === item.href,
                      }}
                    >
                      {item.text}
                    </a>
                  </li>
                ))}
              </ul>
            </>
          ))
        : null}
    </div>
  );
});
