Is this documentation still valid in Studio 3? I can't get it to work. https://www.sanity.io/docs/previews-list-views Edit: I just needed to rename the file, thanks RD.

More importantly, I have a string const for the preview thumbnail image url, I just need to know how to get that string accepted and displayed as the list media

I believe you’ll need to change your file extension to .tsx if you’re using JSX.

Hey did you get this to work?I am getting the error shown in image when trying to use a span with backgroundColor red. File extension is .tsx, react is imported at the top.
code for the preview:

preview: {
    select: {
      title: 'title',
      type: 'campaignItem._type',
      start: 'startTime',
      end: 'endTime',
    }: {
      title: string;
      type: string;
      start: string;
      end: string;
    }) {
      let status = 'Ingen dato';
      const now = new Date().toISOString();
      if (start < now && now < end) {
        status = 'Pågående';
      if (now > end) {
        status = 'Utgått';
      if (start > now) {
        status = `Begynner: ${start}`;
      return {
        subtitle: (
          <span style={{ backgroundColor: 'red' }}>

Do you know if this works for subtitle and title aswell? Like providing some html tags that wraps it then style that tag with a color.It seems to error-out when im using it on anything else than the media key.

Nah, subtitle and title can only take strings or numbers, I believe.
