Help with sorting my bundles/Variant selections out please.

Store Design

Topic summary

Issue: Seeks a variant/bundle selector that uses a single dropdown showing all option combinations, with out‑of‑stock/unavailable choices dimmed and unselectable.

Context: Currently using katching bundles. The existing layout uses two separate dropdowns per variant option. The desired layout consolidates all types into one dropdown and indicates stock status directly in the list.

Clarifications: “Variants” = specific combinations of product options (e.g., size + color). Goal is to improve UX by preventing invalid combinations and clearly signaling availability.

Requests: Looking for recommendations on apps or custom coding to achieve the single combined dropdown with stock-aware disabling and dimming, compatible with bundles.

Assets: Two images provided (current vs. desired UI) are central to understanding the change.

Status: No solutions or app names provided yet; no decisions made. Discussion remains open with the user requesting guidance.

Hello, I am currently using katching bundles, although the first picture is my current bundle layout and the 2nd picture is the one I’m currently looking at changing to, the problem is I’m not sure what type of app the other website is using, it allows me to have all the types in 1 drop down instead of having 2 drop downs for each variant, it also says when the variant is out of stock or is unavailable and dims the wording so you cant select it.

can anyone help me try solve this problem or give suggestions of apps/codeing
