How do I prevent multiple selections in checkboxes?

Surely there has to be a simple way to prevent multiple checkboxes from being selected!

The purpose of a checkbox field is to allow users to select more than 1 option. You can learn more about it here.

Radio Button: Radio buttons are for one choice answer.

Check Box: Used for multiple choices. 

If you want to limit a checkbox field to only have a specified number of options selected, you can change the properties as shown below.
