# Action de règle : Construire un groupe de produits
* Créer une liste de valeurs, par exemple des marques ou des couleurs, à partir de vos produits en fonction d’un ID de groupe.
Utilisez le **Construire un groupe de produits** action pour créer des listes basées sur un identifiant de regroupement, tel que `item_group_id`. Par exemple, vous pouvez créer une liste en utilisant des valeurs provenant de champs spécifiques.
Supposons que nous ayons des données pour des produits de différentes marques et couleurs, et que nous souhaitions créer des listes pour toutes les marques et couleurs.
| id | item\_group\_id | brand | color | brand\_list | color\_list |
| -- | --------------- | ----------- | ------ | ----------- | ----------- |
| 1 | 1 | Nike | White | | |
| 2 | 1 | Adidas | Purple | | |
| 3 | 1 | Puma | Yellow | | |
| 4 | 2 | New Balance | Beige | | |
| 5 | 2 | Vans | Black | | |
| 6 | 3 | Crocs | Green | | |
Si vous utilisez la **Construire un groupe de produits** action et utilisez les `brand` et `color` champs, le résultat sera une liste complète de marques et une liste de couleurs.
| id | item\_group\_id | brand | color | brand\_list | color\_list |
| -- | --------------- | ----------- | ------ | ------------------ | --------------------- |
| 1 | 1 | Nike | White | Nike, Adidas, Puma | White, Purple, Yellow |
| 2 | 1 | Adidas | Purple | Nike, Adidas, Puma | White, Purple, Yellow |
| 3 | 1 | Puma | Yellow | Nike, Adidas, Puma | White, Purple, Yellow |
| 4 | 2 | New Balance | Beige | New Balance, Vans | Beige, Black |
| 5 | 2 | Vans | Black | New Balance, Vans | Beige, Black |
| 6 | 3 | Crocs | Green | Crocs | Green |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://helpcenter.channable.com/manage-improve-product-data/manage-product-and-improve-data-fr/regles-modifier-et-enrichir-en-masse/comment-utiliser-les-actions-alors-dans-les-regles/action-de-regle-construire-un-groupe-de-produits.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
