Related to this point, I am wanting to make the selection box 'stick' when scrolling. Someone else posted this code on another forum, but it didn't work for me:

Qualtrics.SurveyEngine.addOnload(function() {
    setTimeout(function() {
    const container = document.querySelector('.PGRContainerRight'); 

    if (container) {
      container.style.position = 'sticky';
      container.style.top = '20px'; 
      container.style.zIndex = '1000';
      container.style.backgroundColor = '#fff'; 
    }
  }, 500);
});
