# Checkboxes with Exclusive Option (Vue 3)

Checkbox questions include many choice options, and some of them may require special behavior, such as automatically deselecting all other choices when selected. SurveyJS Form Library supports several predefined exclusive options, including [None](https://surveyjs.io/form-library/documentation/api-reference/checkbox-question-model#showNoneItem), [Don't Know](https://surveyjs.io/form-library/documentation/api-reference/checkbox-question-model#showDontKnowItem), and [Refuse to Answer](https://surveyjs.io/form-library/documentation/api-reference/checkbox-question-model#showRefuseItem). In addition, you can make any custom choice exclusive by setting its `isExclusive` property to `true`. In this demo, the "I work from home" option is custom-marked as exclusive, and the built-in Refuse to Answer option is also enabled—either will deselect all other choices when selected.
