There are two main types of selection controls: checkboxes and radio buttons. Checkboxes are the only selection control that allows users to multiselect more than one option or go with zero options. Individual checkbox selection doesn't depend on whether other checkboxes in the list are checked or unchecked.

You can use a standalone checkbox to enable or disable an option, such as granting permission to email on a newsletter signup form or agreeing to terms and conditions.^[1]
