What are the limitations of using standard dropdown elements in PHP for controlling the scroll position of selected items?

Standard dropdown elements in PHP do not inherently have the ability to control the scroll position of selected items. To overcome this limitation, you can use JavaScript to scroll to the selected item after it has been selected in the dropdown element. 

<select id="myDropdown" onchange="scrollToSelected()">
  <option value="1">Option 1</option>
  <option value="2">Option 2</option>
  <option value="3">Option 3</option>
</select>

<script>
function scrollToSelected() {
  var dropdown = document.getElementById("myDropdown");
  var selectedOption = dropdown.options[dropdown.selectedIndex];
  selectedOption.scrollIntoView();
}
</script>
