# Vista de árbol

Cree estructuras de árbol expandibles en las aplicaciones de PowerShell Universal con New-UDTreeView, con compatibilidad para nodos estáticos y carga dinámica al hacer clic en los nodos.

`New-UDTreeView` le permite crear un árbol de elementos y, de forma opcional, expandir dinámicamente la lista al hacer clic.

## Vista de árbol básica

Cree una vista de árbol básica utilizando el 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'
        }
    }
}
```

## Vista de árbol dinámica

Las vistas de árbol dinámicas le permiten ejecutar PowerShell cada vez que se hace clic en un nodo. Después puede devolver una lista de nodos que deberían representarse debajo del nodo en el que se ha hecho clic. También puede realizar otras acciones, como abrir un modal o mostrar una notificación.

```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/es/aplicaciones/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.
