The UI Toggle object is an interactable checkbox with a label.
To create a UI Toggle, select Create | UI | Toggle. By default, a UI Toggle has two children: a Background and a Label. The Background also has a child, a Checkmark.
The Background child is a UI Image that represents the "box" in which the Checkmark UI Image appears. The Label is a UI Text object.
If you want to change the appearance of the box and checkmark, you change the source images of the Image components on the Background and Checkmark children, respectively.
