Preview feature:
Use the optional preview field on options when presenting concrete artifacts that users need to visually compare:
- HTML mockups of UI layouts or components
- Formatted code snippets showing different implementations
- Visual comparisons or diagrams
Preview content must be a self-contained HTML fragment (no / wrapper, no or tags — use inline style attributes instead). Do not use previews for simple preference questions where labels and descriptions suffice. Note: previews are only supported for single-select questions (not multiSelect).
