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.

How to reset a function on "click" using Bootstrap 4 carousel

I'm building a form in Bootstrap 4 that is broken out into multiple parts using a carousel.
What I would like to do is when the user completes the inputs for each section, the "next" button removes the disabled attribute.
I was able to figure this out for the first slide, but I can't figure out how to reset the function when it goes to the next active slide.
I'm trying to use vanilla Javascript. I'd also like to get the validation classes to work for each section using the next button, as opposed to submit.
Any help would be much appreciated. I'm still working to get a lot better at Javascript!
Here is my Fiddle: Guided Carousel

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">

The problem is in this bit:
var linkHref = "home";
$('#myLinks li a').removeClass('active');
$('#myLinks li')
.find('a[href="#' + linkHref + '"]')
.parent()
.find('a')
.tab('show')
.addClass('active')
.attr('data-toggle', 'tab');
$('a.nav-link').not('.active').css('pointer-events', 'none');
I've removed the next() since this will go to the next sibbling (which is the current tab) and adjusted the previous button href to match home.
$("#myTabs form").on('submit', function (e) {
e.preventDefault();
var linkHref = $(this).parents('.tab-pane').attr('id');
$('#myLinks li a').removeClass('active');
$('#myLinks li')
.find('a[href="#' + linkHref + '"]')
.parent()
.next()
.find('a')
.tab('show')
.addClass('active')
.attr('data-toggle', 'tab');
$('a.nav-link').not('.active').css('pointer-events', 'none');
});
$('a.nav-link').not('.active').css('pointer-events', 'none');
$(document).ready(function () {
$("#PrevProduct").click(function (e) {
e.preventDefault();
var linkHref = "home";
$('#myLinks li a').removeClass('active');
$('#myLinks li')
.find('a[href="#' + linkHref + '"]')
.parent()
.find('a')
.tab('show')
.addClass('active')
.attr('data-toggle', 'tab');
$('a.nav-link').not('.active').css('pointer-events', 'none');
});

<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');
});
