# Parameter Sets Widget

## Overview

| Plugin key | BAS Setting key |
| - | - |
| `accelerator_parameter-sets-widget-container` | `bas-plugin-widget-parameter-sets` |

The Parameter Sets widget is one of the What-If tools that can be used to create a What-If in your Atoti Server project. It can be configured to connect to any parameter set datastore, and used to change the values of that datastore.

## How to modify a setting

To modify a setting, you need to modify the `basSettings` that you provide to the `activate` function. The following example shows how to provide the activate function with the default `basSettings` while updating the settings for the Parameter Sets widget:

```javascript theme={"languages":{"custom":["/engine/python-sdk/6.2/languages/pycon.tmLanguage.json"]}}
import { activate, basSettings } from "@activeviam/frtb-sdk";

const frtbServerKey = "FRTB";
const customSettings = structuredClone(basSettings);

customSettings[frtbServerKey]["bas-plugin-widget-parameter-sets"].store =
  "CustomDataStoreName";

activate({
  configuration,
  basSettings: customSettings,
});
```

## How to disable it

### Disable universally

To disable this feature for all solutions, add this line at the end of your extension’s `activate` function to unregister the plugin:

```diff theme={"languages":{"custom":["/engine/python-sdk/6.2/languages/pycon.tmLanguage.json"]}}
const extension: ExtensionModule = {
  activate: async (configuration: Configuration) => {
    ...
+    delete configuration.pluginRegistry["widget"]["accelerator_parameter-sets-widget-container"];
  }
}
```

### Disable for specific servers

To disable this feature for a given server, you must delete this feature’s settings for that server key by altering the `basSettings` parameter before calling the `activate` function.

**Example**
Disabling this feature for the `FRTB` server only:

```diff theme={"languages":{"custom":["/engine/python-sdk/6.2/languages/pycon.tmLanguage.json"]}}
+ import {produce} from "immer";
- import {activate as activateFrtb} from "@activeviam/frtb-sdk";
+ import {activate as activateFrtb, basSettings as frtbBASSettings} from "@activeviam/frtb-sdk";
 import {activate as activeMarketRisk} from "@activeviam/mr-sdk";

 const extension: ExtensionModule = {
  activate: async (configuration: Configuration) => {
    ...
+    const frtbBASSettingsWithFeatureDisabled = produce(frtbBASSettings, draft => {
+      delete draft["FRTB"]["bas-plugin-widget-parameter-sets"];
+    });

-   activateFrtb({configuration});
+   activateFrtb({configuration, basSetttings: frtbBASSettingsWithFeatureDisabled})
    activeMarketRisk({configuration});
  }
}
```
