$("#search").on("keyup", function(){
var search = $(this).val();
if (search !=="") {
$.ajax({
url:" ajax-db-search.php",
type:"POST",
cache:false,
data:{term:search},
success:function(data){
$("#search-result").html(data);
$("#search-result").fadeIn();

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.0/js/bootstrap.min.js">

if (isset($_GET['term'])) {
$query = "SELECT * FROM users WHERE name LIKE '{$_GET['term']}%' LIMIT 25";
$result = mysqli_query($conn, $query);
if (mysqli_num_rows($result) > 0) {
while ($user = mysqli_fetch_array($result)) {
