# Planes

A Form has 100 planes. A Plane can be understood as a page or layer of the Form. You can navigate through the Planes of a Form with the arrows of the “Main Toolbar”.

Any Plane can contain Controls but all the Controls placed on Plane 0 will be visible on all the others. Plane 0 is considered the main Plane so when a Form is opened the Plane 0 is what you’ll see. To change Plane in runtime, use the “[First Plane](/kalipso5/developing/form/actions/actions-description/group-forms/first-plane.md)”, “[Last Plane](/kalipso5/developing/form/actions/actions-description/group-forms/last-plane.md)”, “[Next Plane](/kalipso5/developing/form/actions/actions-description/group-forms/next-plane.md)”, “[Previous Plane](/kalipso5/developing/form/actions/actions-description/group-forms/previous-plane.md)” and “[Go To Plane](/kalipso5/developing/form/actions/actions-description/group-forms/go-to-plane.md)” Actions.

* **Plane** - Plane number. This value is fixed.
* **Name** - Name to give the plane internally. The name of the plane should only contain letters, digits or underscore (\_).
* **Title** - Title for the plane that appears, if desired, in the application.
* **Description** - Description of the plane.

### Edit planes

By clicking on the icon to the right of the table, you can edit the selected plane.

This image shows the options that appear in the table above.

Note that the title option appears an icon that allows you to define different titles for different languages (if the project uses more than one language). Then there is the possibility of putting a title for the languages that were added to the project.

# 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://doc.sysdevmobile.com/kalipso5/developing/form/option-window/planes.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.
