### General settings

| Field                                             | Meaning                                                                                         |
| ------------------------------------------------- | ----------------------------------------------------------------------------------------------- |
| **Activate App**                                  | Master switch per sales channel. Without it neither sliders nor discounts appear.               |
| **Default discount badge background color**       | Background color for badges without an explicit color in the rule. Defaults to `#ff0000` (red). |

| **Max. number products in Cross-selling slider**  | Caps how many products a slider may show at most. Default `10`.                                 |
| **Product sorting in slider**                     | Order of products (name, discount, price, release date — each ascending/descending).            |
| **Always show the "Add to shopping cart" button** | Shows the button right inside the slider — also for parent variant products.                    |

### Slider positions

For every checkout step you choose whether and where the slider appears:

| Setting                                            | Options                                                     |
| -------------------------------------------------- | ----------------------------------------------------------- |
| **Show Cross-selling slider in off-canvas basket** | No · Above basket · Below basket · Bottom of the off-canvas |
| **Show Cross-selling slider in basket**            | No · Above basket · Below basket                            |
| **Show Cross-selling slider in checkout**          | No · Above checkout · Below checkout                        |

## Configure the plugin per sales channel

Use the sales-channel selector at the top of the configuration screen to maintain different settings per shop. To use the plugin in only one shop, leave **Activate App** enabled there and disabled in all other sales channels.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.premsoft.de/en/plugins/cross-selling-for-cart-and-checkout/installation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
