# Non-existent display

Control how option combinations that **don't exist** appear to customers. A non-existent option is a combination that was **never created** as a variant for that product/parent — it has no SKU, no price, and does not show up in the variant list at all. This setting is in **Global settings** and applies to every product.

|| This setting only affects option combinations that were never created. For variants that exist but currently have 0 available stock, see [Out-of-stock display](https://help.optis.me/en/article/out-of-stock-display-109d5k1/).

## Out-of-stock vs. non-existent

|  | Out-of-stock | Non-existent |
| --- | --- | --- |
| **Definition** | The variant exists (has a SKU/price) but available quantity is 0 | The option combination was deleted |
| **Example (Screenshot below)** | *Green / M* — listed among Blue's variants, Available: 0 | *Blue / S* — Blue's variant list only has M and L, so S was deleted |
| **Changes over time?** | Yes — restocking flips it back to available | No — stays fixed until you add a new variant with that combination |

## Display styles

Choose one of four styles:

| Style | What customers see |
| --- | --- |
| **No change** | The option looks the same as any selectable one |
| **Strike-through** | A diagonal line is drawn across the option |
| **Gray out** | The option is dimmed/desaturated so it looks muted |
| **Hide** | The option is removed from the swatches entirely (default) |

|| **Hide** works well when you don't want shoppers to know a combination was never offered. **Strike-through** or **Gray out** keep the option visible so shoppers can see the full range of values (for example, every size) while understanding that this particular color simply doesn't come in that size.
