  $(document).ready(function() {
    var urlCat = window.location.href.split(".com/")[1];
    if (urlCat == "store") {
      var catItem = $('a.nested-category-breadcrumb-link');
      var itemTag = $(catItem).html();
      var catDrop = "<select name='Categories' id='categories' class='catDrop'><option value='All'>All</option>";
      if (itemTag !== undefined) {
        catItem.each(function(i) {
          var fixLoc = $(this).html().trim().replace(/\s+/g, '-').replace(/&/g, '').replace('amp;', '').replace('--', '-').replace(/'/g,'').toLowerCase();
          catDrop = catDrop + '<option value=' + fixLoc + '>' + $(this).html() + '</option>';
          i++;
        });
        catDrop = catDrop + "</select>";
        $(catDrop).insertAfter($('.nested-category-title'));
      }
      if (urlCat !== undefined) {
        var fixCat = urlCat.replace(/\%27/g, "'")
        $(".catDrop").val("All");
      }
      $(".catDrop").change(function() {
        if ($(this).val() == "All") {
          window.location = "/store/";
        } else {
          window.location = "/store/" + $(this).val();
        }
      });
    }
  });
</script>
<style>
  .collection-5f36dfec3a07a2182b139d23 .nested-category-children {
    display: none !important;
  }

  .catDrop {
    margin-top: 2vh;
    margin-bottom: 2vh;
    margin-left: 50%;
    transform: translateX(-50%);
  }
</style>

Use this code

<script>
  $(document).ready(function() {
    var urlCat = window.location.href.split(".au/")[1];
    if (urlCat == "shop4you") {
      var catItem = $('a.nested-category-breadcrumb-link');
      var itemTag = $(catItem).html();
      var catDrop = "<select name='Categories' id='categories' class='catDrop'><option value='All'>All</option>";
      if (itemTag !== undefined) {
        catItem.each(function(i) {
          var fixLoc = $(this).html().trim().replace(/\s+/g, '-').replace(/&/g, '').replace('amp;', '').replace('--', '-').replace(/'/g,'').toLowerCase();
          catDrop = catDrop + '<option value=' + fixLoc + '>' + $(this).html() + '</option>';
          i++;
        });
        catDrop = catDrop + "</select>";
        $(catDrop).insertAfter($('.nested-category-title'));
      }
      if (urlCat !== undefined) {
        var fixCat = urlCat.replace(/\%27/g, "'")
        $(".catDrop").val("All");
      }
      $(".catDrop").change(function() {
        if ($(this).val() == "All") {
          window.location = "/shop4you/";
        } else {
          window.location = "/shop4you/" + $(this).val();
        }
      });
    }
  });
</script>
<style>
  .nested-category-children {
    display: none !important;
  }

  .catDrop {
    margin-top: 2vh;
