+Use the `HasChildren` method when rendering a nested menu.
+
+With this site configuration:
+
+{{< code-toggle file=hugo >}}
+[[menus.main]]
+name = 'Products'
+pageRef = '/product'
+weight = 10
+
+[[menus.main]]
+name = 'Product 1'
+pageRef = '/products/product-1'
+parent = 'Products'
+weight = 1
+
+[[menus.main]]
+name = 'Product 2'
+pageRef = '/products/product-2'
+parent = 'Products'
+weight = 2
+{{< /code-toggle >}}
+
+And this template:
+
+```go-html-template
+<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 renders this HTML:
+
+```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>
+```
