# Vue arborescente

Créez des structures arborescentes extensibles dans les applis PowerShell Universal avec New-UDTreeView, prenant en charge les nœuds statiques et le chargement dynamique lors des clics sur les nœuds.

`New-UDTreeView` vous permet de créer une arborescence d'éléments et, facultativement, d'étendre dynamiquement la liste lorsqu'on clique dessus.

## Vue arborescente de base

Créez une vue arborescente de base en utilisant l'applet de commande `New-UDTreeNode`.

```powershell
New-UDTreeView -Node {
    New-UDTreeNode -Name 'Level 1' -Children {
        New-UDTreeNode -Name 'Level 2 - Item 1' 
        New-UDTreeNode -Name 'Level 2 - Item 2'
        New-UDTreeNode -Name 'Level 2 - Item 3' -Children {
            New-UDTreeNode -Name 'Level 3'
        }
    }
}
```

## Vue arborescente dynamique

Les vues arborescentes dynamiques vous permettent d'exécuter du PowerShell chaque fois qu'un nœud est cliqué. Vous pouvez ensuite retourner une liste de nœuds qui devraient être affichés sous le nœud cliqué. Vous pouvez aussi effectuer d'autres actions, comme ouvrir une fenêtre modale ou afficher un toast.

```powershell
New-UDDashboard -Title 'File System' -Content {
    Get-PSDrive -PSProvider 'FileSystem' | ForEach-Object {
        New-UDTreeView -Node { New-UDTreeNode -Name $_.Name -Id "$($_.Name):\" } -OnNodeClicked {
            Get-ChildItem $EventData.Id | ForEach-Object {
                New-UDTreeNode -Name $_.Name -Id $_.FullName -Leaf:$(-not $_.PSIsContainer)
            }
        }
    }
}
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.devolutions.net/powershell-universal/fr/applis/components/data-display/tree-view.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.
