When you choose a variant 1 (Format) I want see in drop down menuonly the variants (Finish and Frame) available, at the moment it shows all variants and instead shows 'unavailable' where it would normally say 'add to cart'.
Can anyone help me? Thanks :)
If you want to hide unavailable combination from variants box then every time you have to replace variants box on selection because combination only available that you created in admin. so you have to change this in Asset->theme.js file ->find "_onSelectChange" this is your variants selection callback function,
For that you need coding knowledge so if you cant you have to hire developer.
Let me know if you need help.
You must have to take developer support for that as its difficult task for you because all about Js work, if you need let me know i have already done for some store.
