Only with Javascript
I want to create a form and, depends on your choice, you will see some fields or others.
I thought I can do that with a getElementById() and using innerHTML to override all of the forms, however I'm searching for another way that doesn't override all the form and just add a new input

Reset to default 2Using Javascript, all you need is document.createElement and setAttribute.
var input = document.createElement("input");
input.setAttribute('type', 'text');
Then you can use appendChild to append the created element to the desired parent element.
var parent = document.getElementById("parentDiv");
parent.appendChild(input);
Here is a simple example using the createElement, using just javascript you can build nice dynamic forms
<!DOCTYPE html>
<html>
<body>
<p>Click the button.</p>
<button onclick="myFunction()">Add Input Field</button>
<button onclick="myFunctionTwo()">Add Radio button</button>
<script>
function myFunction() {
var x = document.createElement("INPUT");
x.setAttribute("type", "text");
x.setAttribute("value", "You Just added a text field ");
document.body.appendChild(x);
}
function myFunctionTwo() {
var y = document.createElement("INPUT");
y.setAttribute("type", "radio");
document.body.appendChild(y);
}
</script>
</body>
</html>
