pageRef = '/products/product-2'
parent = 'Products'
weight = 2
{
"menus": {
"main": [
{
"name": "Products",
"pageRef": "/product",
"weight": 10
},
{
"name": "Product 1",
"pageRef": "/products/product-1",
"parent": "Products",
"weight": 1
},
{
"name": "Product 2",
"pageRef": "/products/product-2",
"parent": "Products",
"weight": 2
}
]
}
}
以及这个模板
<ul>
{{ range .Site.Menus.main }}
<li>
<a href="{{ .URL }}">{{ .Name }}</a>
{{ if .HasChildren }}
<ul>
{{ range .Children }}
<li><a href="{{ .URL }}">{{ .Name }}</a></li>
{{ end }}
</ul>
{{ end }}
</li>
{{ end }}
</ul>
Hugo 渲染此 HTML
<ul>
<li>
<a href="/products/">Products</a>
<ul>
<li><a href="/products/product-1/">Product 1</a></li>
<li><a href="/products/product-2/">Product 2</a></li>
</ul>
</li>
</ul>
