Multiple Choice question other specify

hi Bérengère You can create a new text entry question for each other and have a display logic on it show it appears only if previous other box is answered.

Don't forget to check "In page" option in display logic. This is how display logic will look like:

Hi,
You can add this javascript code to the addOnReady function :
jQuery("#"+this.questionId+" li.Selection:gt(3)").hide(); // where gt(x) is the first "other specify" choice minus 1
jQuery("#"+this.questionId+" .InputText").focus( function() {
  var isInputText = document.activeElement instanceof HTMLInputElement && document.activeElement.type == 'text';
  if (isInputText) {
      li2 = document.activeElement.parentNode.parentNode.nextSibling.nextSibling.show();
    }
  });

Thanks Guys
