# AppBar

**La App Bar mostra informazioni e azioni relative alla schermata corrente.**

La App Bar superiore fornisce contenuti e azioni relativi alla schermata corrente. Viene utilizzata per il branding, i titoli delle schermate, la navigazione e le azioni.

## AppBar con Drawer personalizzato

![](/files/8Zq2nw2J5qkd84hEEeUM)

```powershell
$Drawer = New-UDDrawer -Children {
    New-UDList -Children {
        New-UDListItem -Label "Home"
        New-UDListItem -Label "Getting Started" -Children {
            New-UDListItem -Label "Installation" -OnClick {}
            New-UDListItem -Label "Usage" -OnClick {}
            New-UDListItem -Label "FAQs" -OnClick {}
            New-UDListItem -Label "System Requirements" -OnClick {}
            New-UDListItem -Label "Purchasing" -OnClick {}
        }
    }
}

New-UDAppBar -Position relative -Children { New-UDElement -Tag 'div' -Content { "Title" } } -Drawer $Drawer
```

## Footer

Per creare una barra dell'app ancorata alla parte inferiore della pagina, può utilizzare il parametro `-Footer`.

```powershell
New-UDAppBar -Children { "Hello" } -Footer
```

## Footer relativo

Un footer relativo rimane sempre nella parte inferiore del documento. Se il contenuto della pagina non occupa il 100% dell'altezza dello schermo, il footer verrà posizionato nella parte inferiore della vista. Se il contenuto supera il 100% dell'altezza dello schermo, il footer sarà visibile solo quando si scorre fino in fondo al corretto.

```powershell
New-UDApp -Title 'PowerShell Universal' -Pages @(
    New-UDPage -Title home -Name home -Blank -HideNavigation -Content {
        New-UDHelmet -Tag 'style' -Content '
            #Footer {
                position: relative;
            }
            #Footer + div {
                display: none
            }
            #content {
                min-height: calc(100vh - 128px);
            }
        '
        New-UDAppBar -Position sticky -ClassName header -DisableThemeToggle -Children {
            New-UDParagraph -Text "Header"
        }
        New-UDElement -Tag 'div' -Content {
            1..100 | % {
                New-UDTypography -Text 'Hello' -Variant h1
            }
        } -Id 'content'
        New-UDAppBar -Id Footer -Footer -Children {
            New-UDParagraph -Text "Footer"
        }
    }
)
```

## AppBar fissa

Una AppBar fissa viene mostrata anche quando la schermata viene fatta scorrere. Rimarrà ancorata in alto. Questo esempio crea una AppBar fissa con un div alto 10000 pixel.

```powershell
New-UDAppBar -Position fixed -Children { New-UDElement -Tag 'div' -Content { "Title" } }

New-UDElement -Tag 'div' -Content {

} -Attributes @{
    style = @{
        height = "10000px"
    }
}
```

## 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/it/app/components/surfaces/appbar.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.
