+## Dataview Support
+
+You can render Dataview queries inside the menu block. The links generated by the query will be styled just like other menu items.
+
+Prefix your query with `dataview:` or `dv:`.
+
+````markdown
+```menu
+layout: default
+[[Home]]
+dataview: LIST FROM "Projects"
+```
+````
+
+Or a more complex query:
+
+````markdown
+```menu
+layout: horizon
+dv: LIST WITHOUT ID link(file.link, file.name) FROM #tag
+```
+````
+
+**Note:** The plugin automatically unwraps the Dataview list structure so the links participate directly in the menu's flex/grid layout.
+
 ## Notes
 
 - Use either `layout:` or `class:`. If the value contains a built-in template, the template is applied. Otherwise, it’s treated as a pure CSS class (no plugin CSS).
