Manual Installation

1. Download the latest release of Select2 from the GitHub repository
2. Extract the files and copy the relevant CSS and JavaScript files into your project directory
3. Include the CSS and JavaScript files in your HTML file

<link href="path/to/select2.min.css" rel="stylesheet" />
<script src="path/to/select2.min.js"></script>

Usage

The following code snippet demonstrates how to initialize Ajax Select2 on an HTML select element:

$('#my-select').select2({
    ajax: {
        url: '/api/my-data',
        dataType: 'json',
        delay: 250,
        processResults: function (data) {
            return {
                results: data.items
            };
        },
        cache: true
    }
});

In this code, #my-select is the ID of the HTML select element. The ajax option specifies the URL where the data is loaded from, the data type of the response, the delay in milliseconds before the search is performed, and how to process the response data. The cache option specifies whether or not to cache the AJAX request.
