Main issue: replicate a multi-step, guided variant selection on a product page (each choice advances to the next step and the screen updates), matching the referenced West & Willow custom pet portraits page.
Key finding: The reference site does not use a third‑party app; it’s hardcoded into the theme (custom build). Achieving the exact flow likely requires custom development.
Suggested app options (to approximate the behavior):
Customization Tool
Easy Product Customizer
Custom Options (listed twice in thread)
Product Options by W3
Advanced Product Options
TEPO Product Options
Inkybay
Implications: Apps may provide conditional options and step-like experiences, but an exact replica of the reference flow may not be plug‑and‑play. Hiring a developer is recommended for a matching experience.
Assets: Shared images illustrate the step‑by‑step flow and are central to understanding the desired UX.
Status: No definitive app solution confirmed; actionable paths are to trial the listed apps or proceed with custom theme development. Discussion remains open without a final resolution.
@annab3 The reference website is not using any app. They have custom built it. For something similar to that you need to hire a developer. If you want I can help you with that. Or try the app suggested by Sweet_savior_3. You can add Inkybay to that list too.
