+### `availableInMatrixColumn`
+
+A Boolean value that specifies whether the property is available in [matrix column](https://surveyjs.io/form-library/documentation/api-reference/multi-select-matrix-column-values) settings. Defaults to `false`.
+
+If you enable this setting, the property will be added to the same [category](#category) and at the same [position](#visibleindex) that it has in a standalone question.
+
+A matrix column's [`cellType`](https://surveyjs.io/form-library/documentation/api-reference/multi-select-matrix-column-values#cellType) must match the class name to which you add the property. For example, the following code adds a property to [Rating Scale](https://surveyjs.io/form-library/documentation/api-reference/rating-scale-question-model) questions and matrix columns of the `"rating"` `cellType`.

 Alternatively, you can [postpone data validation](#postpone-validation-until-survey-ends) until a respondent completes the survey.
 
-> Immediate validation doesn't work with date input fields because of the way browsers process date values. In most browsers, the value is considered changed as soon as a user starts entering the date in a text input field. This means that a user may only enter the day without having the chance to enter the month and year before validation is triggered. For this reason, date input fields are validated before the survey is switched to the next page or completed.

 ## Built-In Client-Side Validators
 
 SurveyJS Form Library supports multiple built-in client-side validators. The Required validator ensures that a question value is not empty. Enable a question's [`isRequired`](https://surveyjs.io/Documentation/Library?id=Question#isRequired) property to add the Required validator to this question. In addition, you can specify the [`requiredErrorText`](https://surveyjs.io/Documentation/Library?id=Question#requiredText) property to override the default error message:

Pass the name of the built-in icon as the first argument and the custom icon markup converted to a string as the second argument. In the following code, a custom icon replaces the `icon-delete` icon:
