# Group

The Group script is assigning a defined group to the component where the group is attached to.

<div align="left"><figure><img src="/files/ud7tBfDoNpRGSw6BJnOb" alt=""><figcaption></figcaption></figure></div>

The Group is named by a GroupName. For Prefabs you can also define a reference to another object which will create a Prefix for the group name. This is especially useful if you would like to generate reusable prefabs that are using the Group function.

The Group scritp is specially used by the [Kinematic](/components-and-scripts/motion/kinematic.md) script.

The [Selection Window](/basics/user-interface/selection-window.md) (available in Pro only) allows you to easily hide and show Groups.
