Guide: HTML5 Datalist: Quick Guide

You’ve probably experienced reactions like this somewhere on the internet: when you type an input form, a list of suggestions appears at the bottom of the input.

Over the years we have relied on JavaScript to create such a function. Today we can do that with the new HTML5 -element. This new HTML5 element allows us to save a list of options that are displayed as the users type the input.

HTML5 list attribute

The can be linked to it element using a new HTML5 attribute, list. We can use list in a few input types such as text and search. But according to Mozilla Developer Network, the list attribute does not apply within the following input types: hidden, checkbox, radio, file, and button

In the following example, we add a list of cities with and assign it an ID attribute, like so.

Around the to a element, simply add a list attribute and reference the id attribute, like so.

Browser behavior

Any browser running the element, Chrome, Opera and Firefox, works slightly differently.

In Chrome, it shows the options starting with the value we enter. In the example below, Chrome shows values ​​starting with “S”

On the other hand, if we click on the entry twice, it will show all available options as shown below.

In Operasince we are focusing on the input form, it immediately shows all the options and then sorts them based on the initial letters we type.

Firefox will not show anything when focusing in the input. It shows the options that contain the values ​​as we type them. For example, this screenshot below shows Firefox with the options containing the letter “YOU”

Safari does not currently support it element and Internet Explorer reportedly supports this element from version 10.

Using HTML5 Datalist with Polyfills

There are a few polyfills to replicate similar functionality in unsupported browsers. In this post, we’ll be implementing Michael Taylor’s datalist polyfills. To use it we need jQuery and Modernizr for the browser feature detection.

As for the Modernizr, we have to make a few adjustments. Check the following options on the Modernizr download page.

  • Enter attributes under the HTML5 section
  • Modernizr.addTest under the Extensibility section
  • Modernizr.load under the Tools section
  • elem datalist among the Non-core

Now let’s open the HTML document in which we have the element and the Modernizr library we just downloaded in the section.

After adding Modernizr, we can test the browser if it supports the datalist element with the script below.

if (! Modernizr.datalistelem) {alert (‘This browser doesn’t support HTML5 datalist element, so we’ll load the polyfills’);}

The above script displays a warning saying “This browser does not support HTML5 datalist element, so we will load the polyfills” if datalist element is not supported. In Safari it looks like this.

Then create a new JavaScript file called load.datalist.js and add this line below it. This will direct and output the script to the input with the list attribute.

$ (‘input’) .datalist ();

Finally, we load the jQuery, jquery.datalist.js and load.datalist.js with Modernizr.load as follows.

Modernizr.load ({test: Modernizr.datalistelem, no:

So they are only loaded if the browser uses the element.
