What are some alternative methods to Select2 and jQuery for enhancing user input in PHP forms with large datasets?

When dealing with PHP forms that involve large datasets, it can be challenging to provide users with an efficient way to input data. Select2 and jQuery are commonly used for enhancing user input in such scenarios, but there are alternative methods available. One approach is to use AJAX to dynamically load data based on user input, reducing the initial load time and improving user experience. 

// PHP code snippet using AJAX to dynamically load data for user input

// HTML form with input field
<form>
    <input type="text" id="inputField" onkeyup="getData(this.value)">
    <select id="dataList"></select>
</form>

// JavaScript function to fetch data using AJAX
<script>
function getData(input) {
    $.ajax({
        url: 'getData.php',
        method: 'POST',
        data: {input: input},
        success: function(response) {
            $('#dataList').html(response);
        }
    });
}
</script>

// PHP script (getData.php) to fetch and return data based on user input
<?php
$input = $_POST['input'];
// Fetch data based on user input
// Return data as options for select dropdown
?>
