VisualizaçõesHow to add new lines after HTML elements
I have a simple method for adding input boxes after a button is clicked. The goal of this method is to generate a set of input boxes with a newline inserted after each div.
In the screenshot above you can see that the divs are spaced properly. However, when the add_more button is clicked the generated inputs do not come out properly.
Expected: The code should generate new input boxes like so:
<div>
Key Term 2: <input id="el2" type="text" value=""> <br>
</div>
<br>
Actual:
function add_more() {
// we've added more inputs.
addMore = true;
// set html generated to false, because new inputs have been added.
htmlGenerated = false;
// increment the number of inputs.
numberOfInputs++;
//fetch the input boxes.
inputs = document.getElementById("inputBoxes");
// create newline
br_key = document.createElement("br");
// create newline
br_description = document.createElement("br");
//create a new row for a key term.
row = document.createElement("div");
// set the key term text.
row.innerHTML = "Key Term ";
row.innerHTML += numberOfInputs;
row.innerHTML += " :";
// create the input for the key.
key = document.createElement("input");
key.setAttribute("id", "el" + numberOfInputs);
//add the key to the row.
row.appendChild(key);
row.after(br_key);
//create a row for the new description.
row2 = document.createElement("div");
// set the description text.
row2.innerHTML = "Description "
row2.innerHTML += numberOfInputs;
row2.innerHTML += " :";
// create the description input
description = document.createElement("input");
description.setAttribute("id", "dl" + numberOfInputs);
// add the description to the row.
row2.appendChild(description);
row2.after(br_description);
// add the rows for the key and the description to the inputBoxes.
inputs.appendChild(row);
inputs.appendChild(row2);
}<div>Key Term 5 :<input id="el5"></div>Any help figuring out this issue would be greatly appreciated. Thanks.

Your issue here is essentially incorrect HTML, CSS. I'd implement your inputs, etc. like this:
.full-width-label {
display:block;
}<label class="full-width-label" for="1">Label</label>
<input type="text" id="1"/>There are multiple ways to achieve the above, this is just one of your options but now you no longer need to embed the look into the HTML and the format of your HTML (line breaks) is independent of your look.
You might want to look into an off the shelf solution for these kinds of things, like Bootstrap or Tailwind

You can use make it in a simple way
HTML
add this jquery cdn
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js">
</script>
<button type="button">Click Here</button>
<div class="appendDiv">
</div>
Js
$(document).ready(function (){
var button = document.getElementsByTagName('button');
var appendDiv = document.getElementsByClassName('appendDiv');
var key = 1;
var descKey = 1;
$('button').click(function(event){
event.preventDefault();
$(appendDiv).append('<div class="child"><div class="grand-child"><label>Key Form :'+ ' '+(++key)+'</label><input type="text" value=""/></div><div class="grand-child"></div><label>Description :'+ ' '+(++descKey )+'</label><input type="text" value=""/></div>');
})
})
