# DRAGNDROP

## Overview

The `DRAGNDROP` class provides constants for handling drag-and-drop operations in Servoy. Key operations include `COPY`, `MOVE`, and `NONE`, which allow developers to define behavior for copying, moving, or disabling drag functionality. These constants help streamline interaction handling in custom applications. Additionally, the class defines MIME types such as `MIME_TYPE_SERVOY` and `MIME_TYPE_SERVOY_RECORD`. These constants ensure proper identification of Servoy objects and records during drag-and-drop operations, enhancing integration and compatibility within the Servoy runtime environment.
