+title: Menu definition file
+---
+
+# Menu definition file
+
+A menu definition file allows you to control the layout and structure of the menu on the left side of the Infrahub web interface. More information can be found in the [Controlling the menu guide](/guides/menu).
+
+The menu definition file is a YAML file that follows a particular structure or schema.
+
+At the top of the file we define a bit of boilerplate statements, to define the version of the schema of the file and the kind of content that it contains. We also define a spec mapping with a data key.
+
+```yaml
+---
+apiversion: infrahub.app/v1
+kind: Menu
+spec:
+  data:
+```
+
+The value of the data key in the spec mapping, is a sequence (or list) that of menu items.
+
+A menu item is a mapping in which you can define the following key/value pairs:
+
+| Key          | Type     | Description                                                                 | Mandatory          |
+|--------------|----------|-----------------------------------------------------------------------------|--------------------|
+| name         | string   | the name of the menu item                                                   | :white_check_mark: |
+| namespace    | string   | the namespace of the menu item                                              | :white_check_mark: |
+| label        | string   | the name of the menu item in UI                                             | :x:                |
+| kind         | string   | selecting this menu item will take you to the list view of this schema node | :x:                |
+| path         | string   | selecting this menu will take you to this path (URL)                        | :x:                |
+| icon         | string   | the icon of the menu item                                                   | :x:                |
+| order_weight | integer  | controls the ordering of menu items (lower values are ordered first)        | :x:                |
+| children     | sequence | list of nested menu items                                                   | :x:                |
