The ByWeight method returns the given menu with its entries sorted by [weight], then by name, then by identifier. This is the default sort order.

Consider this menu definition:
hugo.
menus:
main:
- identifier: about
name: About
pageRef: /about
weight: 20
- identifier: services
name: Services
pageRef: /services
weight: 10
- identifier: contact
name: Contact
pageRef: /contact
weight: 30
[menus]
[[menus.main]]
identifier = 'about'
name = 'About'
pageRef = '/about'
weight = 20
[[menus.main]]
identifier = 'services'
name = 'Services'
pageRef = '/services'
weight = 10
[[menus.main]]
identifier = 'contact'
name = 'Contact'
pageRef = '/contact'
weight = 30
{
"menus": {
"main": [
{
"identifier": "about",
"name": "About",
"pageRef": "/about",
"weight": 20
},
{
"identifier": "services",
"name": "Services",
"pageRef": "/services",
"weight": 10
},
{
"identifier": "contact",
"name": "Contact",
"pageRef": "/contact",
"weight": 30
}
]
}
}
To sort the entries by weight, then by name, then by identifier:
<ul>
{{ range .Site.Menus.main.ByWeight }}
<li><a href="{{ .URL }}">{{ .Name }}</a></li>
{{ end }}
</ul>
Hugo renders this to:
<ul>
<li><a href="/services/">Services</a></li>
<li><a href="/about/">About</a></li>
<li><a href="/contact">Contact</a></li>
</ul>
You can also sort menu entries using the [sort] function. For example, to sort by weight in descending order:
<ul>
{{ range sort .Site.Menus.main "Weight" "desc" }}
<li><a href="{{ .URL }}">{{ .Name }}</a></li>
{{ end }}
</ul>
When using the sort function with menu entries, specify any of the following keys: Identifier, Name, Parent, Post, Pre, Title, URL, or Weight.
