Hello, my product has many variants. After using plugins, many variants will be displayed.
Example: https://nailtrendlab.com/product/lilycue-6pcs-set-glitter-gel-nail-polish-nude-red-brown-color-gel-polish-semi-permanent-nail-art-gel-vernis-for-manicure-kits/
Can we only display some variants, which will only appear when the customer selects’ more ‘? I have debugged a lot, but I have not found how to implement it yet. Can you help me?
Thank you
