# `QuestionNonValue`

A base class for question types that cannot have a value ([Html](https://surveyjs.io/form-library/documentation/questionhtmlmodel), [Image](https://surveyjs.io/form-library/documentation/questionimagemodel)).

This class does not implement new functionality—it only redefines default values of certain properties inherited from the [`Question`](https://surveyjs.io/form-library/documentation/question) class.

## Inheritance

[`Base`](https://surveyjs.io/form-library/documentation/api-reference/base.md) → [`SurveyElementCore`](https://surveyjs.io/form-library/documentation/api-reference/surveyelementcore.md) → [`SurveyElement`](https://surveyjs.io/form-library/documentation/api-reference/surveyelement.md) → [`Question`](https://surveyjs.io/form-library/documentation/api-reference/question.md) → `QuestionNonValue`
