and what i tried in my template :
{% for ee in test.products %}
{{ ee.description }}
<br />
{% endfor %}

Ok so theres a couple issues here:
First of all you actually need to define what is gonna happen when you submit the form, so in your view do this:
views.py
def home(request):
categories = Category.objects.annotate(test=Count('product')).filter(test__gt=0)
if request.method == 'POST':
test = CartForm(request.POST)
if form.is_valid():
cart = form.save(commit=False)
for product in request.POST.getlist('products'):
cart.add(product)
else:
pass
else:
form = CartForm()
return render(request, 'boutique.html', {"categories": categories, "test": test})
then in your template you actually have to render the form (test):
boutique.html
<form method="post">
{% csrf_token %}
{{ test.as_p }}
<button type="submit"> Add Items </button>
</form>
Now you should see the list of products in template.
edit
if you want to show a different model field in your form rewrite its __str__ method like this:
def __str__(self):
return self.description # to show description
