When select different options shows different input, but all inputs of all options are required

I'm working with Django and I made a function that creates a person (employee, student, or worker) and as you can see I created the three different forms on create_person, so on the template, when you select an option on school_role to choose what kind of person you will create, its shows different inputs and select, it depends if you click on student, academic or employee. This is ok, but my problem is that I need to fill all of the inputs and selects on all of the three options to be able to send the form, and I need that you just have to fill one ( employee, academic, or student).
def create_person(request):
if request.method == 'POST':
form = PersonForm(request.POST)
daysform = AvailableDayForm(request.POST)
studentForm = StudentForm(request.POST)
academicForm = AcademicForm(request.POST)
employeeForm = EmployeeForm(request.POST)
if form.is_valid() and daysform.is_valid():
data = form.save()
daysform.save(id=data.id)
id = data.id
if(data.school_role==1):
if studentForm.is_valid():
studentForm.save(id = id)
messages.success(
request=request,
message='success'
)
return redirect('cases:list')
elif(data.school_role == 2):
if academicForm.is_valid():
academicForm.save(id = id)
messages.success(
request=request,
message='success'
)
return redirect('cases:list')
else:
if employeeForm.is_valid():
employeeForm.save(id = id)
messages.success(
request=request,
message='success'
)
return redirect('cases:list')
else:
form = PersonForm()
daysform = AvailableDayForm()
studentForm = StudentForm()
academicForm = AcademicForm()
employeeForm = EmployeeForm()
context = {
'form': form,
'studentForm': studentForm,
'academicForm': academicForm,
'employeeForm': employeeForm,
'daysform': daysform
}
return render(request, 'person/create_person.html', context)
This is the template create_person.html:
<div class="columns">
<div class="column">
<h1 class="title">New person </h1>
</div>
</div>
<div class="card">
<div class="card-content">

{% endfor %}
{% for field in form %}
<div class="field">
<div class="control">
<label for="{{ field.id_for_label }}" class="label">

</label>
{% if field.field.widget.input_type == 'select' %}
{%if field.name == 'school_role'%}
<div class="select">
<select onchange="yesnoCheck(this);" name = "school_role" required>
<option value="">--------</option>

</select>
</div>
<div id="ifStudent" style="display: none;">
{% for field in studentForm %}
<label for="{{ field.id_for_label }}" class="label">

</label>
{% if field.field.widget.input_type == 'select' %}
<div class="select">
{{ field }}
</div>
{% else %}
{{ field }}
{% endif %}
{% for error in field.errors %}
<p class="help is-danger">{{ error }}</p>
{% endfor %}
{% endfor %}
</div>
<div id="ifAcademic" style="display: none;">
{% for field in academicForm %}
<label for="{{ field.id_for_label }}" class="label">
{{field.label}}
</label>
{% if field.field.widget.input_type == 'select' %}
<div class="select">
{{ field }}
</div>
{% else %}
{{ field }}
{% endif %}
{% for error in field.errors %}
<p class="help is-danger">{{ error }}</p>
{% endfor %}
{% endfor %}
</div>
<div id="ifWorker" style="display: none;">
{% for field in employeeForm %}
<label for="{{ field.id_for_label }}" class="label">
{{field.label}}
</label>
{% if field.field.widget.input_type == 'select' %}
<div class="select">

</div>
{% else %}
{{ field }}
{% endif %}
{% for error in field.errors %}
<p class="help is-danger">{{ error }}</p>
{% endfor %}
{% endfor %}

{% endif %}
{% else %}
{{ field }}
{% endif %}
{% for error in field.errors %}
<p class="help is-danger">{{ error }}</p>
{% endfor %}
</div>
</div>
{% endfor %}
And this is my script.
function yesnoCheck(that) {
if (that.value == "1") {
document.getElementById("ifStudent").style.display = "block";
} else {
document.getElementById("ifStudent").style.display = "none";
}
if (that.value == "2"){
document.getElementById("ifAcademic").style.display = "block";
} else {
document.getElementById("ifAcademic").style.display = "none";
}
if (that.value == "3"){
document.getElementById("ifWorker").style.display = "block";
}else{
document.getElementById("ifWorker").style.display = "none";
}
}

Counter variable not updating correctly

EDIT:
As several of you pointed out, the "submit" type reloads the page each time, so a running count is not maintained. I fixed this by using sessionStorage to store the number. Here's the fixed code:
function addItem(){
window.sessionStorage.setItem('count',Number(window.sessionStorage.getItem('count'))+1);
/*if(currentItems>3){
currentItems=3;
}*/
console.log("Item added");
update();
}
function removeItem(){
window.sessionStorage.setItem('count',Number(window.sessionStorage.getItem('count'))-1);
/*if(currentItems<0){
currentItems=0;
}*/
console.log("Item removed");
update();
}
function update(){
console.log(Number(window.sessionStorage.getItem('count')));
}
Original Question:
I don't have much experience in JS so forgive me if this is a silly question. I created the following script to count the number of items added to a bundle of products:
var currentItems=0;
function addItem(){
++currentItems;
/*if(currentItems>3){
currentItems=3;
}*/
console.log("Item added");
update();
}
function removeItem(){
--currentItems;
/*if(currentItems<0){
currentItems=0;
}*/
console.log("Item removed");
update();
}
function update(){
console.log(currentItems);
}
The addItem and removeItem events are triggered by "onclick" tags on certain buttons. When I check the console, it correctly shows the "Item added" and "Item removed" messages, but it displays the wrong number for currentItems. When I click a button that should trigger addItems, the console displays 1 regardless of how many items I've added. Similarly, when I click a button that triggers removeItems, the console displays -1. It seems like the variable is starting from 0 each time I click. Any ideas on how to fix this?
EDIT:
Here's the full code. I'm building a custom template within the Bundle Builder Shopify App, so everything aside from the CSS styling and my script are default.

Lemonstand makes radio buttons able to select more than one, how do I fix?

I can change the "checkbox" to "radio" but it still allows more than one to be selected. What can I do to only allow a single selection? Here's the site: https://winkdiapers.com/product/os-pocket-diaper
<div class="clearfix">
{% for index, extra in product.extras %}
<div class="extra">
<label class="title" for="{{ 'extra-'~index }}">
{% if extra.enabled %}
<input type="checkbox" id="{{ 'extra-'~index }}" {{ checkbox_state(postedExtras[extra.id], extra.id) }} name="extras[{{ extra.id }}]" data-ajax-handler="shop:product" data-ajax-update="#product-page=shop-product">
{% else %}
<input type="checkbox" disabled="disabled">
{% endif %}
{{ extra.name }} ({{ extra.price|currency }})</label>
</div>
{% endfor %}
</div>

Customizing Dropdown on Shopify Product Page (Single Variant)

Working with one variant in Shopify on the product page dropdown, and would like it grayed out when not available (sold out).
Here's the code I have so far: (for the entire page)
{% include 'buyx-product' with product %}
{% include 'buyx-price-min' with product %}
{% assign option_to_match = settings.option_to_match %}
{% assign option_index = 0 %}
{% for option in product.options %}
{% if option == option_to_match %}
{% assign option_index = forloop.index0 %}
{% endif %}
{% endfor %}
{% if buyx_product_available %}
<form action="/cart/add" method="post" class="clearfix product_form" data-money-format="{{ shop.money_format }}" data-option-index="{{ option_index }}" id="product-form-{{ product.id }}">
{% if product.options.size > 1 and (product.options[1] != "BuyXDiscount") %}
<div class="select">
<select id="product-select-{{ product.id }}" name='id'>
{% for variant in product.variants %}
{% unless variant.title contains '% Off' %}
<option value="{{ variant.id }}">{{ variant.title }}</option>
{% endunless %}
{% endfor %}
</select>
</div>
{% elsif buyx_select_one_option and (product.variants.size > 1 or product.options[0] != "Title" or product.options.first != 'BuyXDiscount') %}
<div class="select">
<label>{{ product.options[0] }}:</label>
<select id="product-select-{{ product.id }}" name='id'>
{% for variant in product.variants %}
{% unless variant.title contains '% Off' %}
<option value="{{ variant.id }}">{{ variant.title }}</option>
{% endunless %}
{% endfor %}
</select>
</div>
{% else %}
<input type="hidden" name="id" value="{{ product.variants.first.id }}" />
{% endif %}
{% include 'swatch' with 'Color' %}
{% if settings.display_product_quantity %}
<div class="left">
<label for="quantity">Quantity:</label>
<input type="number" min="1" size="2" class="quantity" name="quantity" id="quantity" value="1" />
</div>
{% endif %}
<div class="purchase clearfix {% if settings.display_product_quantity %}inline_purchase{% endif %}">
{% if settings.cart_return == 'back' %}
<input type="hidden" name="return_to" value="back" />
{% endif %}
<input type="submit" name="add" value="Add to Cart" class="action_button add_to_cart" />
</div>

{% endif %}
Unfortunately, what's happening is that instead of the product with 0 inventory being grayed out, the product prior to the product with 0 inventory is being grayed out. For example, in the screenshot below, size 9.5 is the size with zero inventory, but size 9 is showing as grayed out.

When I say manually, I mean something like this...
<select>
{% for variant in product.variants %}
{% if variant.available %}
<option value="{{variant.id}}">{{variant.title}}</option>
{% else %}
<option value="{{variant.id}}" disabled>{{variant.title}}</option>
{% endif %}
{% endfor %}
</select>

Perhaps instead of using the for loop index, you could select the option with the corresponding variant title or id? Something like this:
{% unless variant.available %}
jQuery('.single-option-selector option[value="{{ variant.title }}"]').attr('disabled', 'disabled');
{% endunless %}
This answer might also be useful:
jQuery('.single-option-selector option:contains({{ variant.title | json }})')...
although option:contains may not work in your situation where you have sizes like 9 and 9.5.
EDIT:
From the link you provided, it looks like Size is option2, so try this:
jQuery('.single-option-selector option[value="{{ variant.option2 }}"]').attr('disabled', 'disabled');

How to make first radio button selected by default in a list built with a for in loop using twig?

I'm using twig to make a list of radio buttons with Database values. It's something like:
{% for usermembershiptype in usermembershiptypes %}
<div class="ms_type noline">
<p>{{ usermembershiptype.description}}</p>
<label class="ms_price ms_odd">${{ usermembershiptype.price }}<span>/year</span><input name="membership-type" type="radio" value="{{ usermembershiptype.id }}"/></label>
<div class="clearfix"></div>
</div>
{% endfor %}
I want the first radio button to be selected by default but when using a for in loop, I'm not sure about how to refer to the first radio button.
Any advices? Javascript and Jquery Solutions are also welcome.

You can use the loop.index and if condition like
{% for usermembershiptype in usermembershiptypes %}
<div class="ms_type noline">
<p>{{ usermembershiptype.description}}</p>
<label class="ms_price ms_odd">${{ usermembershiptype.price }}<span>/year</span>
{% if loop.index == 1 %}
<input name="membership-type" type="radio" value="{{ usermembershiptype.id }}" checked/>
{% else %}
<input name="membership-type" type="radio" value="{{ usermembershiptype.id }}"/>
{% endif %}
</label>
<div class="clearfix"></div>
</div>
{% endfor %}
Note: not tested
Using loop.first
{% for usermembershiptype in usermembershiptypes %}
<div class="ms_type noline">
<p>{{ usermembershiptype.description}}</p>
<label class="ms_price ms_odd">${{ usermembershiptype.price }}<span>/year</span>
{% if loop.first %}
<input name="membership-type" type="radio" value="{{ usermembershiptype.id }}" checked/>
{% else %}
<input name="membership-type" type="radio" value="{{ usermembershiptype.id }}"/>
{% endif %}
</label>
<div class="clearfix"></div>
</div>
{% endfor %}
