               menu widget

Provide the widget with a content page
      that contains your menu:

{{ widgets::menu(content="_common/menus/main.md") }}

Separate entries with a thematic break:
    either ---, ~~~, ___ or <hr />

An entry can be either text, a link, or
a submenu. A submenu is an actual list
   defined using Markdown or HTML.

 You cannot use <p> tags in the menu.
