In most cases, there is a field on forms that allows for auto-completion of user input. This can be achieved using the HTML <datalist>. The <datalist> tag works with the input tag to enable users to quickly fill in data on forms by presenting them with a dropdown list of pre-defined options. In this article, we will explain how to create an input suggestion form using HTML and CSS, and demonstrate how to use the <datalist> tag to enable the auto-completion feature on your website.
Note: The element’s id attribute used in the <datalist> tag should be equal to the element’s list attribute in the <input> tag which will help to bind them together.
Syntax:<datalist> ... </datalist> Preview:.png) Approach:- Create a div with the class as a container. Inside this div, create another div with a class as a ‘text container’ that will contain the <input> tag & <datalist> tag.
- Declare the list attribute as a text container inside the <input> tag. Similarly, declare the id attribute as the same as the list attribute, inside the <datalist> tag.
- Now, create the drop-down list of programming languages for building the pre-defined options.
We have used google font to build some awesome input forms & for decorating the text. In order to use the google font, we need to import the following font URL in our stylesheet.
@import url(‘https://fonts.googleapis.com/css2?family=Roboto+Condensed:ital,wght@0,300;0,400;0,700;1,300;1,400;1,700&display=swap’);
Example : This example illustrates the use of the <datalist> tag to make input suggestions in HTML.
