<h2>Search/Filter Dropdown</h2>


<div class="dropdown">

<script>
/* Javascript function to search the list*/
function filterFunction() {
  let input, filter, ul, li, a, i;
  input = document.getElementById("myInput");
  /* change everything to lower or upper case in order 
  to make the search case insensitive */
  filter = input.value.toUpperCase(); 
  div = document.getElementById("myDropdown");
  li = div.getElementsByTagName("li");
  for (i = 0; i < li.length; i++) {
    txtValue = li[i].textContent || li[i].innerText;
    if (txtValue.toUpperCase().indexOf(filter) > -1) {

    } else {
      li[i].style.display = "none";
