Hey folks, how would I preview content on an object that has an array of media? Ideally I’d like to show an icon depending on whether is media is a video or an image.

! You can create a custom preview . In your
function, you'll want to conditionally render your icon. If you share your schema and the fields you're checking against I can be more specific.

, here’s the schema for the object:

export default {
  title: "Media Section",
  name: "mediaSection",
  type: "object",
  fields: [
      title: "Media",
      name: "media",
      type: "array",
      of: [{ type: "img" }, { type: "video" }],
      validation: (Rule) => Rule.max(3),
  preview: {
    select: {
      title: "media.0.alt",
      media: "media.0",
      mediaType: "media.0._type",
    prepare({ title, media, mediaType }) {
      return {
        title: title,
        media: media,
        icon: mediaType == "image" ? FiImage : FiFilm,

another question (I am trying to replicate your question):Would you like the preview to be only the icon or would you like to have an additional icon next to a preview of the uploaded `img`/`video`?
There are different ways to do so, and the schema you shared is about both as far as I can see…

You can specify an icon in the `img`/`video` schemas, which will then be displayed in the options in
+ Add Item
(see pic) or add an icon in the preview of the array in the Media section.

, I would like only one thing to show. Ideally, if it’s an image, we preview the image. And if it’s a video, then show the icon (I’m using vimeo so I don’t think we can preview the asset directly?)

The icons show up in the “Media section” array as intended, but I would like to show the preview in the the parent component aka the “Project contents” array as well so that it’s easy to know what’s in each “Media section”

ah! So can you add this schema as well? 🙂
