Issues with array field and reference type in navMenu schema

The closest I've gotten is by passing an empty span, but that looks horrible. The media's html element in the preview list container has a fixed height and width. I would expect that if I specifically pass null or false to the media property, that it would hide it altogether.

UPDATE: solved, but not sure if this is the best way
Okay, I've got another related issue: The screenshot above is of my navMenu schema. I've set up a field of type
and it can take custom objects such as
, but it can also take a
type to itself,
, so that I can have sub menus. My issue is I'm not getting the expected data in the list previews. What's odd to me (because I'm still learning Sanity) is that the correct icon will show up for the
type, but for everything else I'm getting
. I'm probably doing something wrong.
If I do it like this:

   name: "items",
   title: "Menu Items", // e.g. 'Categories', 'Sale'
   type: "array",
   of: [
     { type: "menuItemWithIcon" }, // e.g. 'New Arrivals', 'Tops', etc.
     { type: "menuItemWithImage" },
     { type: "reference", to: [{ type: "navMenu" }] },
   validation: (Rule) => [Rule.min(1), Rule.unique()],
the result is like this:

As you can see, the validation is working, as are the titles, but I want to use a different icon to better represent a submenu item.

So I resorted to something I did in another schema, but feels hacky:

    // doing this so I can alter the appearance of the menuItem in the dropdown, but I lose the ability to reference the data in the preview
    name: 'submenu',
    title: 'Sub Menu',
    type: 'object',
    icon: BsListNested,
    preview: {
       select: {
          title: 'navMenu',
       prepare({ title }) {
           console.log('title', title);
           return {
             title: title,
             media: BsListNested,
     fields: [
          name: 'submenuReference',
          type: 'reference',
          to: [{ type: 'navMenu' }],
and the result I get with this spaghetti code is:

I don't know what to select in the preview object. Everything I try comes back as
Jun 11, 2023, 1:36 PM
Golly bum! I know I tried this
title: 'submenuReference.title'
and was still getting
, but now it's working as expected. However, do I really have to define an inline object like that to achieve the desired result or is there a more concise way?
