# Display Flexible UI Pages

## Command 0x1830 - Display Flexible UI Pages (Display Only) <a href="#ref201815442" id="ref201815442"></a>

This command allows the host to bring up standalone pages. A page is considered standalone if it’s stateless, meaning it will be:

* Shown on the display.
* Can allow user input.
* Returns user input result to the host.
* Operation ends.

## 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://developer.magtek.com/hardware/card-readers/mms-dyna-devices/dynaflex-ii-ped/documentation/developers-manuals/dynaflex-ii-ped-programmers-manual/commands/user-interface/display-flexible-ui-pages.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.
