Sold-out and unavailable values
Two different situations make a value impossible to buy. The app treats them separately, so shoppers can tell a colour that's sold out from a combination that was never made.
| Situation | Example | Setting |
|---|---|---|
| Sold out | Red / M exists, but has no stock left. | Out of stock style |
| Unavailable combination | Red only comes in S and M, so XL doesn't exist once Red is chosen. | Unavailable combination behavior |
What counts as sold out
A variant is sold out when Shopify says it can't be purchased. Variants that don't track inventory, or that keep selling when out of stock, count as available.
Choose how sold-out values look
- 1
Open Settings
Go to Settings and find Variant picker defaults.
- 2
Pick an Out of stock style
Choose one of the four styles below. The preview beside it shows sample swatches with two sold-out values.

Fine-tune it
For Strikethrough, set the Sold-out line color. For Opacity, set how faded sold-out swatches and buttons look.

Save
Click Save in the save bar.
| Style | Result | Settings |
|---|---|---|
| Fixed | Sold-out values look like any other value. | None |
| Strikethrough | A line is drawn across sold-out values. The default. | Sold-out line color, red #D72C0D to start |
| Opacity | Sold-out values are faded. | Sold-out fade (swatches) and Sold-out fade (buttons), 10 to 100 %, 60 % to start |
| Hidden | Sold-out values are removed from the row. | None |
Product cards follow the same style
On product cards, sold-out values are struck through or faded the same way, and Hidden leaves them off the card. On a card, a value counts as sold out when none of its variants can be bought.
Choose what happens to combinations that don't exist
As a shopper picks one option, the others react. A value that doesn't exist with the current choice can fade or disappear:
- 1
Open Settings
Go to Settings and find Product page.
- 2
Choose the behavior
Under Unavailable combination behavior, choose Fade (the value stays visible but faded) or Hide (the value disappears until the shopper changes their other choice).

Unavailable combination behavior in Settings - 3
Save
Click Save.
Tip
Fade is the safer choice for most stores: shoppers still see every option that exists, and nothing jumps around as they click.
Troubleshooting
- The variant tracks inventory in Shopify and Continue selling when out of stock is off. Otherwise it counts as available.
- You clicked Save on the Settings page.
- The product page uses the app's picker, not the theme's (see Add swatches to product pages).
