Custom Select Input with search option in HTML, CSS, and Javascript

Hello friends, today in this blog, we will learn how to create a custom select input with a search option in HTML, CSS, and Javascript. In our previous blog, we saw how to create a responsive image lightbox design using HTML, CSS, and Vanilla Javascript. Now it's time to create a custom select input with a search option. If you are interested then you can check my other javascript projects after reading this blog. My javascript blogs.

The custom select menu is a dropdown menu that allows users to select or choose a particular option that is predefined. In this menu, there is a select input with a search box as you can see in the image above.

On this select menu, there are many countries as an option and users can select any country at a time. There is a search input also that is used to search anything quickly from the options. If you want to check the demo then you can check the source code and demo as well.
