# Conditions

Utilisez le composant Condition dans les widgets du portail PowerShell Universal pour afficher du contenu de façon conditionnelle selon le résultat d'un bloc de script PowerShell.

Vous pouvez utiliser le composant `<Condition />` dans les widgets pour afficher facultativement des sections du widget.

## Bloc de script

Utilisation de l'attribut `ScriptBlock` pour définir un bloc de script qui détermine la valeur de la condition. Le bloc de script doit retourner true ou false.

```xml
<Condition ScriptBlock="$Errors -eq $null">
</Condition>
```

## Contenu enfant

La section `ChildContent` sera affichée si la condition est vraie.

```markup
<Condition ScriptBlock="$Errors -eq $null">
   <ChildContent>
      <Alert Message="Success!" />
   </ChildContent>
</Condition>
```

## Else

La section `Else` sera affichée si la condition est fausse.

```markup
<Condition ScriptBlock="$Errors -eq $null">
   <ChildContent>
      <Alert Message="Success!" />
   </ChildContent>
   <Else>
      <Alert Message="Failure!" Type="error" ShowIcon="true" />
   </Else>
</Condition>
```

## 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://docs.devolutions.net/powershell-universal/fr/portal/portal-widgets/conditions.md?ask=<question>&goal=<user_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.
