{{% note "Lazy Blogger"%}}
|
||
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).
|
||
{{% /note %}}
|

|
||
You can do this:
|
||
|
||
* Place content in one or many menus
|
||
* Handle nested menus with unlimited depth
|
||
* Create menu entries without being attached to any content
|
||
* Distinguish active element (and active branch)
|
||
|
||
## What is a Menu in Hugo?
|
||
|
||
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`.
|
||
|
||
{{% note "Menus on Multilingual Sites" %}}
|
||
If you make use of the [multilingual feature](/content-management/multilingual/), you can define language-independent menus.
|
||
{{% /note %}}
|
||
|
||
A menu entry has the following properties (i.e., variables) available to it:
|
||
|
||
`.URL`
|
||
: string
|
||
|
||
`.Name`
|
||
: string
|
||
|
||
`.Menu`
|
||
: string
|
||
|
||
`.Identifier`
|
||
: string
|
||
|
||
`.Pre`
|
||
: template.HTML
|
||
|
||
`.Post`
|
||
: template.HTML
|
||
|
||
`.Weight`
|
||
: int
|
||
|
||
`.Parent`
|
||
: string
|
||
|
||
`.Children`
|
||
: Menu
|
||
|
||
Note that menus also have the following functions available as well:
|
||
|
||
`.HasChildren`
|
||
: boolean
|
||
|
||
Additionally, there are some relevant functions available to menus on a page:
|
||
|
||
`.IsMenuCurrent`
|
||
: (menu string, menuEntry *MenuEntry ) boolean
|
||
|
||
`.HasMenuCurrent`
|
||
: (menu string, menuEntry *MenuEntry) boolean
|
||
|
||
## Add content to menus
|
||
|
||
Hugo allows you to add content to a menu via the content's [front matter](/content-management/front-matter/).
|
||
|
||
### Simple
|
||
|
||
If all you need to do is add an entry to a menu, the simple form works well.
|
||
|
||
#### A Single Menu
|
||
|
||
```
|
||
---
|
||
menu: "main"
|
||
---
|
||
```
|
||
|
||
#### Multiple Menus
|
||
|
||
```
|
||
---
|
||
menu: ["main", "footer"]
|
||
---
|
||
```
|
||
|
||
#### Advanced
|
||
|
||
|
||
```
|
||
---
|
||
menu:
|
||
docs:
|
||
parent: 'extras'
|
||
weight: 20
|
||
---
|
||
```
|
||
|
||
## Add Non-content Entries to a Menu
|
||
|
||
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].
|
||
|
||
Here’s an example snippet pulled from a configuration file:
|
||
|
||
{{< code-toggle file="config.toml" >}}
|
||
[[menu.main]]
|
||
name = "about hugo"
|
||
pre = "<i class='fa fa-heart'></i>"
|
||
weight = -110
|
||
identifier = "about"
|
||
url = "/about/"
|
||
[[menu.main]]
|
||
name = "getting started"
|
||
pre = "<i class='fa fa-road'></i>"
|
||
weight = -100
|
||
url = "/getting-started/"
|
||
{{< /code-toggle >}}
|
||
|
||
{{% note %}}
|
||
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`.
|
||

|
||
|
||
## Nesting
|
||
|
||
All nesting of content is done via the `parent` field.
|
||
|
||
The parent of an entry should be the identifier of another entry. The identifier should be unique (within a menu).
|
||
|
||
The following order is used to determine an Identifier:
|
||
|
||
`.Name > .LinkTitle > .Title`
|
||
|
||
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.
|
||
|
||
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.
|
||
|
||
## Render Menus
|
||
|
||
See [Menu Templates](/templates/menu-templates/) for information on how to render your site menus within your templates.
