In this article, I take you step by step on how to implement or add an autocomplete dropdown below your input to suggest possible values in your form based on searched data by the end-user.

You can also populate the list of autocomplete options dynamically as well which i will share with you very soon on the channel(Oston Code Cypher) and here.

Absorbing this amount of content would be alot if you are just reading it,so i have put together a very simple video for you.

In the next video we will use AJAX and PHP in order to fetch data from the database on a fly or Asynchronously(Without page reload).

HTML MARKUP

Make sure you give your input element a class of autocomplete because it will be the one we hold on when selecting it in javascript.

copy

	
<html>

<head>
	<title>Auto Complete</title>
</head>
<body>

	<h4>AutoComplete search</h4>

	<!-- input element -->
	<div class="input-field">
	<input type="text" class="autocomplete">
	<label>Search</label>
	</div>

</body>
</html>

JAVASCRIPT & INITIALIZATION

The data is a json object where the key is the matching string and the value is an optional image url(Watch Video).

copy

document.addEventListener('DOMContentLoaded',function(){

const inputField =document.querySelector('.autocomplete');

M.Autocomplete.init(inputField,{
	data:{
		'Google':null,
		'Yahoo':null,
		'Youtube':null,
		'OstonCode':null
	},
	limit:'infinit',

});

});
