# UI Page Option 0x00 Layout

The host uses this option to display a maximum of 5 lines of host-provided text, and 1 optional green functional button, Middle – label with a String ID that associates it with a configured String message. See **Table – Default User Interface String IDs and Strings**. 

When the user presses this button, the device sends a notification to the host to indicate this button is pressed. See **User Interface Host Action Request - Notification 0x1803.** After that, the host will decide what to do next.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/api-and-command-reference/scra-dynafamily-programmers-manual/commands/user-interface-command-group-0x18nn/display-flexible-ui-pages-display-only-command-0x1830/ui-page-option-0x00-layout.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.
