Hi, i have an online grocery store.

In the past i was able to select variant options but than Shopify had an update and now I am unable to select variant options.

For e.g. We have chicken and we need to select how we would like the chicken, With Skin? YES/NO, Cuttings (Size)? WHOLE, 2, 4, 8, 12

The problem is that it some times adds this to the trolley and sometimes doesn’t when clicked on ‘Done’. It does not allow us to add the quantity at all.

How can we select the variants and add the quantity to the trolley whenever chosen?

Your help will be greatly appreciated,

Sham

Thank you for wanting to help me folablizz, however i believe you misunderstood my question.

I know how to change or update the variant but the customised code which shows the variant on a product rather than a new page is not functioning the way it should be. If you had the chance to check the link I sent you would better understand ( https://happiroo.co.uk/collections/vegetables and select Okra).

Appreciate your input.
