Multiline Textbox

Totally. Here’s an example.

New-UDDashboard -Title 'Title' -Content {
    New-UDRow -Columns {
        New-UDColumn -LargeSize 6 -Content {
            New-UDCodeEditor -Language markdown -Id 'code' -Height 400
            New-UDButton -Text 'Render' -OnClick {
                Sync-UDElement -Id 'output'
            }
        }
        New-UDColumn -LargeSize 6 -Content {
            New-UDDynamic -Id 'output' -Content {
                $Code = (Get-UDElement -Id 'code').code                
                New-UDHtml ($Code | ConvertFrom-Markdown).Html
            }           
        }
    }
}
