# Componentes personalizados

Los componentes de las aplicaciones de PowerShell Universal se exponen como funciones. Puede combinar componentes integrados para crear sus propios componentes personalizados.

## Ejemplo: selector de personas

<figure><img src="/files/c4sN0WIrHTt7lI6H64dd" alt=""><figcaption><p>Selector de personas</p></figcaption></figure>

El siguiente ejemplo crea un componente `New-UDPeoplePicker` a partir de componentes de aplicación existentes. Puede utilizar el componente `New-UDPeoplePicker` en sus aplicaciones. Esta función puede definirse directamente en su aplicación o dentro de un [Module](/powershell-universal/es/plataforma/modules.md).

Este ejemplo utiliza una carpeta publicada de avatares.

```powershell
function Get-User {
    1..100 | ForEach-Object {
        [PSCustomObject]@{
            UserName = "User$_"
            First = "Bill"
            Last = $_
            Avatar = (Get-ChildItem "$Repository\Avatars" | Get-Random).Name
        }
    }
}

function New-UDPeoplePicker {
   $Session:Users = [System.Collections.Generic.List[object]]::new()

    New-UDAutocomplete -OnLoadOptions {
        Get-User | Where-Object { $_.UserName -like "*$UserName*" } | Select-Object -First 5 -ExpandProperty 'UserName' | ConvertTo-Json 
    } -OnChange {
        $Session:Users.Add((Get-User | Where-Object { $_.UserName -eq $EventData })) | Out-Null
        Sync-UDElement -Id 'users'
    }

    New-UDDynamic -Id 'users' -Content {
        New-UDList -Children {
            $Session:Users | ForEach-Object {
                New-UDListItem -Label $_.UserName -SubTitle "$($_.First) $($_.Last)" -AvatarType 'Avatar' -SecondaryAction {
                    $UserName = $_.UserName
                    New-UDIconButton -Icon (New-UDIcon -Icon 'Trash') -OnClick {
                        $RemoveUser = $Session:Users | Where-Object { $_.UserName -eq $UserName }
                        $Session:Users.Remove($RemoveUser) 
                        Sync-UDElement -Id 'users'
                    }
                } -Source "/avatars/$($_.Avatar)"

            }    
        }
    }
}

New-UDApp -Title 'PowerShell Universal' -Content {
    New-UDPeoplePicker
}
```

## 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/custom-components.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.
