### Examples

#### Example 1: Basic alert

```powershell
New-UDStack -Content {
   New-UDAlert -Severity 'error'  -Title "Error" -Id 'alert1'
   New-UDAlert -Severity 'warning' -Title "Warning" -Id 'alert2'
   New-UDAlert -Severity 'info'  -Title "Info" -Id 'alert3'
   New-UDAlert -Severity 'success' -Title "Success" -Id 'alert4'
} -Direction 'column'
```

The alert offers four severity levels that set a distinctive icon and color.

#### Example 2: Text and Title

```powershell
New-UDStack -Content {
   New-UDAlert -Severity 'error' -Title 'Error' -Text 'This is an error alert' -Id 'alert5'

   New-UDAlert -Severity 'success' -Title 'Success' -Text 'This is an success alert' -Id 'alert8'
} -Direction 'column'

You can use the -Title parameter to display a formatted title above the content.

   New-UDAlert -Severity 'warning' -Title "Warning" -Id 'alert10' -Dense

## 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/powershell-commands/new-udalert.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.
