# Arborescence

`New-UDTreeView` vous permet de créer une arborescence d'éléments et, facultativement, de développer dynamiquement la liste lorsqu'un élément est cliqué.

## Arborescence de base

Créez une arborescence de base en utilisant la cmdlet `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'
        }
    }
}
```

## Arborescence dynamique

Les arborescences dynamiques vous permettent d'exécuter du code PowerShell chaque fois qu'un nœud est cliqué. Vous pouvez ensuite retourner une liste de nœuds à afficher sous le nœud cliqué. Vous pouvez également effectuer d'autres actions, comme ouvrir une boîte de dialogue modale ou afficher une notification.

```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)
            }
        }
    }
}
```
