Forms are an integral part of many websites. They are used to gather user information, feedback, and more. With JavaScript, it is possible to create form fields dynamically, allowing developers to add, remove, and manipulate form elements in real-time. This can be particularly useful for users who need to input multiple pieces of information, as well as for developers who want to create more dynamic and interactive forms.
In this article, we will explore the process of creating form fields dynamically with JavaScript. We will cover the basics of creating form elements and manipulating them with JavaScript, as well as some more advanced techniques for making your forms even more dynamic and engaging.
To create Fields dynamically using JavaScript, we can use the document.createElement method to create the element. Then we can use the setAttribute method to set the element attributes and finally we can use the appendChild method to append the elements into the parent element.

Prerequisites:
Before starting this tutorial, you should have a basic understanding of HTML, CSS, and JavaScript. Additionally, you will need a code editor such as Visual Studio Code or Sublime Text to write and save your code.
Source Code
Step 1 (HTML Code):
The first thing we need to do is create our HTML File. I've only included three fields, two of them (Name and Email) are static and I make another Field dynamic, on which we will be performing the actions.
After creating the files just paste the below HTML codes into your file. Make sure to save your HTML document with a .html extension, so that it can be properly viewed in a web browser.
This is the basic structure of our dynamically form fields using HTML, and now we can move on to styling it using CSS.
Step 2 (CSS Code):
Once the basic HTML structure of the form fields is in place, the next step is to add styling to the form fields using CSS. CSS allows us to control the visual appearance of the website, including things like layout, color, and typography.
Next, we will create our CSS file. In this file, we'll style the form fields with CSS to make them look more presentable. This can include things like setting widths and heights, adding borders, and changing the font.
This will give our dynamic form fields an upgraded presentation. Create a CSS file with the name of styles.css and paste the given codes into your CSS file. Remember that you must create a file with the .css extension.

} Step 3 (JavaScript Code):
The final step in creating dynamic form fields using HTML, CSS, and JavaScript is to add and remove form fields dynamically using JavaScript. JavaScript allows us to create dynamic and interactive elements on the website.
Adding form fields with JavaScript is a straightforward process. First, you need to create a new form field element using the document.createElement method. Next, you need to set the properties of this element, such as its type, name, and value. Finally, you need to add the element to your form using the appendChild method.
Removing form fields with JavaScript is just as easy as adding them. To remove a form field, you simply need to find the element you want to remove and use the removeChild method to remove it from the form.
Create a JavaScript file with the name of script.js and paste the given codes into your JavaScript file and make sure it's linked properly to your HTML document, so that the scripts are executed on the page. Remember, you’ve to create a file with .js extension.
