I’m trying to code a volume bundle:

URL: Glow Curtain: 400 LED Lights for a Magical Ambiance – InteriorGlows

CODE: Jan 09 5:36 PM - Codeshare

I’m displaying multiple variant selectors at the same time, because I want to allow the user to add different variants to cart at the same time from the bundle. The issue I’m having though is that when I change a variant selector, the buy-button gets unavailable. Does anyone know how I can fix this issue to allow different variants to be added to cart at the same time.
