# Tree View
`New-UDTreeView` ermöglicht es Ihnen, einen Baum von Elementen zu erstellen und die Liste optional beim Klicken dynamisch zu erweitern.
## Einfache Tree View
Erstellen Sie eine einfache Tree View mit dem 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'
}
}
}
```
## Dynamische Tree View
Dynamische Tree Views ermöglichen es Ihnen, PowerShell auszuführen, wenn auf einen Knoten geklickt wird. Sie können dann eine Liste von Knoten zurückgeben, die unterhalb des angeklickten Knotens gerendert werden sollen. Sie können auch andere Aktionen ausführen, etwa ein Modal öffnen oder einen Toast anzeigen.
```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)
}
}
}
}
```

## 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/de/apps/components/data-display/tree-view.md?ask=&goal=
```
`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.
