==================

Hi! I would like to do answer codes visible on a survey. 
I tried this but it didn't work: forums.limesurvey.org/forum/can-i-do-thi...swer-codes-in-survey
I found some code but it uses "imput value" which in radio butom its ok but in multiple options question appears "Y - ":

document.addEventListener("DOMContentLoaded", function () {
  document.querySelectorAll('.answer-item').forEach(function (item) {
    const input = item.querySelector('input');
    const label = item.querySelector('label');
    if (input && label) {
      const code = input.value;
      const text = label.textContent.trim();
      label.textContent = `${code} - ${text}`;
    }
  });
});

Do you know some javascript that i can copy to custom.js and works for all type of question? Or some javascript i can use for multiple option questions? 

Thanks in advance.
