Can You Upgrade Food Items?

Hi guys, trying to put together a restaurant website -- I can't seem to see any functionality to be able to charge additional "upcharge" for adding on an item to your product.

For instance. You select a 2 piece fried chicken product with fries. I can list other options from fries that would cost the same, but perhaps I want to charge more for onion rings, there is no functionality to do that, so I cannot add "up-sell's or upcharges" to the site? Is this correct, is there a workaround? Any help would be great. Thanks!

Is there any actual support from Squarespace that isn't paid? I mean it's a simple question on functionality. Really regretting my purchase now and thinking of just scrapping the $70 I paid to move to Wix... Can anyone advise please?

This is a Squarespace community forum but you can contact Squarespace Customer Care directly for free support using this link.

Does anyone have any updates for this? I'm looking to be able to do a Build Your Own Juice, and need the same functionality. Thanks!

You could have up to 100 variants in step with product, but there is not a bundling or package deal option on the Squarespace platform like this but, so it is not possible to have checkboxes for unique version options. Each one will be displayed within the identical dropdown container.
