Released: January 11, 2024

SurveyJS v1.9.125 implements a capability to prevent duplicate responses in rows of a Single-Select Matrix, introduces an API to specify default titles for questions created based on custom question types, and includes other enhancements and bug fixes.

A Single-Select Matrix displays multiple survey questions with identical answers in a table form and allows respondents to select one answer in each row. If you want the answers to be unique across all rows, you can now enable a new eachRowUnique property for your Single-Select Matrix:

const surveyJson = {
  "elements": [{
    "type": "matrix",
    // ...
    "eachRowUnique": true
  }]
}

If a respondent submits duplicate answers, the matrix displays a validation error:

SurveyJS Form Library enables you to create custom specialized and composite question types to customize and group form fields. However, previous SurveyJS versions didn't allow you to specify a default question title that would be used instead of a question name when Survey Creator users create a new question based on your custom question type or when Form Library displays the custom question in a form. SurveyJS v1.9.125 support this capability using a new defaultQuestionTitle property, which is part of the ICustomQuestionTypeConfiguration interface. This property accepts a default question title as a string value or as an object that defines different titles for different locales:

import { ComponentCollection } from "survey-core";

ComponentCollection.Instance.add({
  // ...
  defaultQuestionTitle: "Default title"
});
// ===== OR =====
ComponentCollection.Instance.add({
  // ...
  defaultQuestionTitle: {
    en: "Default title",
    de: "Standardtitel",
    fr: "Titre par défaut"
  }
});
