# Checkbox

A checkbox survey answer allows respondents to select multiple options from a predefined list of choices. This question type is ideal when you want to enable participants to choose more than one answer within the same question.

To render your survey question answers as a checkbox make sure to set the multiple selection option on on your survey [question properties](/form-management/form-designer/questions/question-properties.md).
