    20  {{% note "Lazy Blogger"%}}
    21  If all you want is a simple menu for your sections, see the ["Section Menu for Lazy Bloggers" in Menu Templates](/templates/menu-templates/#section-menu-for-lazy-bloggers).
    22  {{% /note %}}
    23  
    24  You can do this:
    25  
    26  * Place content in one or many menus
    27  * Handle nested menus with unlimited depth
    28  * Create menu entries without being attached to any content
    29  * Distinguish active element (and active branch)
    30  
    31  ## What is a Menu in Hugo?
    32  
    33  A **menu** is a named array of menu entries accessible by name via the [`.Site.Menus` site variable][sitevars]. For example, you can access your site's `main` menu via `.Site.Menus.main`.
    34  
    35  {{% note "Menus on Multilingual Sites" %}}
    36  If you make use of the [multilingual feature](/content-management/multilingual/), you can define language-independent menus.
    37  {{% /note %}}
    38  
    39  See the [Menu Entry Properties][me-props] for all the variables and functions related to a menu entry.
    40  
    41  ## Add content to menus
    42  
    43  Hugo allows you to add content to a menu via the content's [front matter](/content-management/front-matter/).
    44  
    45  ### Simple
    46  
    47  If all you need to do is add an entry to a menu, the simple form works well.
    48  
    49  #### A Single Menu
    50  
    51  ```
    52  ---
    53  menu: "main"
    54  ---
    55  ```
    56  
    57  #### Multiple Menus
    58  
    59  ```
    60  ---
    61  menu: ["main", "footer"]
    62  ---
    63  ```
    64  
    65  #### Advanced
    66  
    67  
    68  ```
    69  ---
    70  menu:
    71    docs:
    72      parent: 'extras'
    73      weight: 20
    74  ---
    75  ```
    76  
    77  ## Add Non-content Entries to a Menu
    78  
    79  You can also add entries to menus that aren’t attached to a piece of content. This takes place in your Hugo project's [`config` file][config].
    80  
    81  Here’s an example snippet pulled from a configuration file:
    82  
    83  {{< code-toggle file="config.toml" >}}
    84  [[menu.main]]
    85      name = "about hugo"
    86      pre = "<i class='fa fa-heart'></i>"
    87      weight = -110
    88      identifier = "about"
    89      url = "/about/"
    90  [[menu.main]]
    91      name = "getting started"
    92      pre = "<i class='fa fa-road'></i>"
    93      weight = -100
    94      url = "/getting-started/"
    95  {{< /code-toggle >}}
    96  
    97  {{% note %}}
    98  The URLs must be relative to the context root. If the `baseURL` is `https://example.com/mysite/`, then the URLs in the menu must not include the context root `mysite`. Using an absolute URL will override the baseURL. If the value used for `URL` in the above example is `https://subdomain.example.com/`, the output will be `https://subdomain.example.com`.
    99  {{% /note %}}
   100  
   101  ## Nesting
   102  
   103  All nesting of content is done via the `parent` field.
   104  
   105  The parent of an entry should be the identifier of another entry. The identifier should be unique (within a menu).
   106  
   107  The following order is used to determine an Identifier:
   108  
   109  `.Name > .LinkTitle > .Title`
   110  
   111  This means that `.Title` will be used unless `.LinkTitle` is present, etc. In practice, `.Name` and `.Identifier` are only used to structure relationships and therefore never displayed.
   112  
   113  In this example, the top level of the menu is defined in your [site `config` file][config]). All content entries are attached to one of these entries via the `.Parent` field.
   114  
   115  ## Render Menus
   116  
   117  See [Menu Templates](/templates/menu-templates/) for information on how to render your site menus within your templates.
