# RuntimeForm

## Overview

The `Form` class offers a powerful interface for interacting with runtime forms in Servoy, providing access to core properties and behaviors essential for dynamic UI and data handling. It facilitates interaction with foundsets, elements, variables, and responsive containers, enabling developers to create and manage forms programmatically.

## Features and Capabilities

The class supports retrieving and modifying foundsets, accessing form elements, and leveraging responsive form containers for advanced styling and layout customization. It also provides properties for interacting with controllers, allowing developers to enable or disable form components dynamically.
