 ```typescript
     forContentTypeAlias: ['product', 'anotherContentTypeAlias'],
+    forBlockEditor: ['block-list', 'block-grid', 'block-rte'],
 ```
 
+Depending on the values, the custom view is applied to the following data types:

+- `block-list` - For more information, see the [Block List editor](../fundamentals/backoffice/property-editors/built-in-umbraco-property-editors/block-editor/block-list-editor.md).
+- `block-grid` - For more information, see the [Block Grid editor](../fundamentals/backoffice/property-editors/built-in-umbraco-property-editors/block-editor/block-grid-editor.md).
+- `block-rte` - Blocks used inline in the [Rich Text editor](../fundamentals/backoffice/property-editors/built-in-umbraco-property-editors/rich-text-editor/blocks.md).
