Dynamically creating tabs in bootstrap, with each new tab having the same default content?

I want to make a page such that I start off with Landing Page and Add Tab[+]. Then if I click add tab, I get a New Tab, with a blank version of the Landing Page Template. I'm using Bootstrap for front end and Python for back end.

Is there Any way that the HREF can popup this?

When this code pops up as a form it works well, but when I press "Don't have an Account.." it redirects to the Parent Directory.
Can someone help?
document.querySelector("#linkCreateAccount").addEventListener("click", e => {
e.preventDefault();
loginForm.classList.add("form--hidden");
createAccountForm.classList.remove("form--hidden");
});
<div class="header">
<ul class="headerList">
<li id="item"> Home</li>

<li id="item"> Contact us</li>
<li id="popup-login">
<button onclick="togglePopup()">Login/Register</button>
<div class="popup" id="popup-1">
<div class="overlay"></div>
<div class="content">
<div class="close-btn" onclick="togglePopup()">×</div>
<form class="form" id="login">
<h1 class="form__title">Login/Register</h1>
<div class="form__message form__message--error"></div>
<div class="form__input-group">
<input type="text" class="form__input" autofocus placeholder="Username or email">
<div class="form__input-error-message"></div>
</div>
<div class="form__input-group">
<input type="password" class="form__input" autofocus placeholder="Password">
<div class="form__input-error-message"></div>
</div>
<button class="form__button" type="submit">Continue</button>
<p class="form__text">
Forgotten your password?
</p>
<p class="form__text">
<a class="form__link" href="./" id="linkCreateAccount">Don't have an account? Create account?</a>
</p>
</form>

The problem is that by clicking on the button you are clicking on a link <a> with href="./".
The solution for this case should be: implementing javascript trigger instead of usual html-link:
<a class="form__link" href="void(0);" onclick="toggleCreateAccountPopup()" id="linkCreateAccount">Don't have an account? Create account?</a>
Here, href is voided, and JS-trigger toggleCreateAccountPopup() is called - instead of linking to parent dir.

How to validate in each step the required fields? (that is, the next button should only work if required fields are valid and not empty)

I´m creating a multi-step form using bootstrap and jquery with 4 steps.
But I want that in each step validate the required fields, that is, the button to go to the next step should only work if the required fields are not empty.
But I´m not having success implementing this part of validating each step the required fields. Do you know how to do that?
Working example: https://jsfiddle.net/4vzf9qgr/2/
Jquery:
$(function(){
// navigation buttons
$('a.nav-link').on('show.bs.tab', function (e) {
var $target = $(e.target);
if ($target.parent().hasClass('disabled')) {
e.preventDefault();
}
});
$(".next-step").click(function (e) {
var $active = $('.nav-pills li a.active');
$active.parent().next().removeClass('disabled');
nextTab($active);
});
$(".prev-step").click(function (e) {
var $active = $('.nav-pills li a.active');
prevTab($active);
});
function nextTab(elem) {
$(elem).parent().next().find('a.nav-link').click();
}
function prevTab(elem) {
$(elem).parent().prev().find('a.nav-link').click();
}
});

One way to do it is to use the div IDs that you have ("#step1", "#step2", etc) and have the button be disabled unless the following function returns true:
function validateForm(divId)
{
var inputs, index;
var form=document.getElementById(formId);
inputs = form.getElementsByTagName('input');
for (index = 0; index < inputs.length; ++index) {
// deal with inputs[index] element.
if (inputs[index].value==null || inputs[index].value=="")
{
alert("Field is empty");
$(buttonID).prop('disabled', true);
return
}
}
$(buttonID).prop('disabled', false);
}
Update/Additional comments:
I changed the function above to set the button instead of returning anything. At form load, have the button be disabled. Then add an onfocus attr to run an event listener like this:
function validateFormListener(divID, formObject) {
formObject.addEventListener("input", function(evt) {
validateForm(divID, buttonID)
})
}
Give the button an ID, then replace buttonID in the examples with this name. Change the input tags to look like this:
<input type="text" required class="form-control" onfocus="validateFormListener('#step1', buttonID, this)" name="conference_name" id="conference_name">

jquery ready event is not working when bootstrap modal is called

I have created a jquery menu as I have links in my li, which is generated by a framework and can not have control over it.
I have created the snippet for my code. It works fine on document load. No issues.
I have another bootstrap button for sign in and sign up.
As i click on button it breaks my menu which created with jQuery and show all links without nesting. It seems like it calls another event and it breaks it.
It will be great help if some one help to tackle this sort of issue.
Thanks.

document.ready is called when the DOM is loaded, not when the modal is opened.
You want to bind to the modal open event.
$('#modal-content').on('shown.bs.modal', function() {
$("#txtname").focus();
})

I have got my code working by adding this function to my jQuery
$(document).ready(function(){
$.fn.chunk = function(size) {
var arr = [];
for (var i = 0; i < this.length; i += size) {
arr.push(this.slice(i, i + size));
}
return this.pushStack(arr, "chunk", size);
}
buildNavMenus();
$( document ).ajaxComplete(function() {
buildNavMenus();
});
});
in buildNavMenus(); I have added my code to create nested menu.

jQuery onclick modal

<script>
$( "#id1" ).click(function() {
$( "#myModal" ).click();
});
</script>
It seems everything is okay for me, initial it was work but suddenly it is giving trouble, so what would be the mistake.
When ever I have click on register it is not pop-up the form, could you please let me know what mistake I have done.

$( "#id1" ).click(function(ev) {
ev.stopImmediatePropagation(); // sometimes click event fires twice in jQuery you can prevent it by this method.
$( "#myModal" ).modal(); // you should use native function of Bootstrap.
});

You dont need to add any jquery or js for that at first place.
So you need to add data-target attribute to target your myModal,
<li id="id1 "> Register</li>
So you markup should look like,
<ul class="loginbar pull-right">
<li class="hoverSelector"><i class="fa fa-globe"></i>
Help</li>
<li class="topbar-devider"></li>
<li id="id1 "> Register</li>
<li class="topbar-devider"></li>
<li><a>Login</a></li>
</ul>
Alternate to your js requirement you could do it on click of a tag,
$('ul.loginbar').on('click', 'li#id1 > a', function(){
$('div#myModal').modal('show');
});
