{% hint style="warning" %}

A parent menu item can only expand or fold the submenu items. You cannot link an app to it.

When you delete a parent menu item, all submenu items under it are deleted at the same time.

{% endhint %}

Add URL query parameters or hash parameters to a menu item with `key` and `value`.

Then click the menu item on the canvas, and the parameters are appended to the URL of the app to be opened. You can check in **Globals** tab in the left pane.

{% hint style="info" %}

To reference the url parameters, use `{{url.query.key1}}` or `{{url.hash.key1}}` in your app.

{% endhint %}

For more information of URL parameters, see Go to app.

By default, a menu item is hidden for users without app permission. When you toggle this option off, the users can see the menu item but can not view the app it references to.

The permissions for navigations are the same as those for modules and apps. See Permissions for resources.
