V13.5.2 For a carousel I'm trying to replicate Nested Content with a Block List within a Block Grid Block while using the Umbraco.Community.BlockPreview package. The overall Carousel is a Block Grid Block called "Image Carousel". It's element type just has a "Carousel List" Block List of "Carousel Item"s. Each "Carousel Item" holds an image, link and caption info. I have a View for the "Image Carousel" and it displays ok on the front end. But in the back end, I can see the image and info in the page but not in the flyout editors. Do I need another View for the "Carousel Item" or won't it work with the BlockPreview package?

Hey @Craig100! Yes, if you want the editors in the side panel to have previews, that block list editor will need the preview file adding to each data type

So is that back to manual methods in the app_plugin folder then?

Nope you can still use BlockPreview! Edit the Carousel List datatype, then click on the Carousel Item block in there and add a Custom View

Ah, I see, you mean a custom view as in /Views/Partials/blockgrid/Components. Great, I'll give that a go. Thanks 🙂

You should already have a view for your Block List item in /Views/Partials, adding the

block-preview.html

as the Custom View for that Block List block should link everything together

This is starting to do my head in. I can see the end result in the back office, but if I click to open it I get an error for each carousel item. However, if I click on each of the errorred items, I see the correct representation of the carousel item. https://cdn.discordapp.com/attachments/1309251944828899388/1309492674260369418/image.png?ex=6741c796&is=67407616&hm=d1f21960734d9fd937b26fbf5b2ea25efdd004d064570114479a08643c9df384&

Have you got a Block Grid partial called Carousel Item too? It looks as though the partial it’s trying to load is inheriting from BlockGridItem rather than BlockListItem

That was it! It's always (usually) the little things. I was inheriting BlockGridItem. Thanks. 🙂
