Yes/No Question

A Yes/No, or Boolean, question asks respondents to select between two options: yes or no, true or false, etc. Boolean questions can be used to implement conditional survey logic or as standalone questions. This example demonstrates how to create and configure a Boolean question in SurveyJS Form Library. Switch between Angular, React, Knockout, jQuery, and Vue to view an example for your JavaScript framework.

To create a Boolean question, define an object with the type property set to "boolean" and add it to the elements array. Within this object, specify the question's title and a unique name that identifies the question.

A Boolean question displays "Yes" for the positive answer and "No" for the negative answer. Use the labelTrue and labelFalse properties to change the displayed text labels. In this demo, you can use Settings to change the labels at runtime.

Survey results store true or false as an answer to a Boolean question. If you want to save custom values instead, assign them to the valueTrue and valueFalse properties. You will still be able to access the selected Boolean value via the booleanValue property. In this demo, Boolean questions save "Yes" or "No" in survey results.

Boolean questions support the following UI modes:

• Slider
• Radio button group
• Checkbox

The slider mode automatically applies when labels are short; the radio button group mode—when they are long. To use a specific display mode, set the renderAs property to "radio" or "checkbox". This example demonstrates all three display modes.
