Scrolling a big list of countries, states or cities is annoying sometimes when you are filling a form asking your country to select. Today I come up with a solution to make a searchable drop-down list, very happy to share it with you :).
Today in this tutorial I will tell you how to make a searchable drop-down list in HTML, CSS. You can create a static dropdown but I am creating it to dynamic. Check this demo.
Problem
As you know the problem, that’s why you are here for the solution. LOL…, So the problem is this, suppose you have created a form in your website or web application, you have a long dropdown list to select it as you might have seen on a variety of websites. You need to scroll it until you did not find the item you are looking for.
Solution
The solution is select2. Select2 is a jQuery based replacement for select boxes. It supports searching remote data sets and infinite scrolling of results.
When you will integrate this, you will get a search box at the top of the select dropdown list. Now you can search the item you are looking for in a long list. You can check the installation guide also on the official website.
<link href="https://cdn.jsdelivr.net/npm/select2@4.0.12/dist/css/select2.min.css" rel="stylesheet" />
<script src="https://cdn.jsdelivr.net/npm/select2@4.0.12/dist/js/select2.min.js"></script>
Import these CDN links to the head of the HTML page and paste this shortcode to the footer to make your dropdown list searchable.
// In your Javascript (external .js resource or <script> tag)
$(document).ready(function() {
$('.your-select-dropdown-class').select2();
});
Don’t worry I will show you how to code step by step. I am creating this select 2 dropdown list dynamic by fetching the countries from the database. Let’s check the folder structure.
Addidtionally, I will show country flags in the dropdown, to make it more beautifull and eye catchy to the users.
Step by step to code
- Create an index.php file to show the select dropdown list.
- config.php is the connection file to the database.
- flags folder contains all the flags of the countries. I will provide it.
Now create these files.
index.php complete code

function formatState (state) {
if (!state.id) {
return state.text;
}
var baseUrl = "flags";
var $state = $(
'<span><img src="' + baseUrl + '/' + state.element.value.toLowerCase() + '.png" class="img-flag" /> ' + state.text + '</span>'
);
return $state;
}
</script>

config.php
<?php
$connection = new mysqli("localhost","root","","codingbirds");
if (! $connection){
die("Error in connection".$connection->connect_error);
}
