selecting some form inputs and show it to the user

Question

I want to be able to select only required fields and show it to my frontend, this is the html template. create_employee.html

      {% for field in form %}
          <div class="form-group{% if field.errors %} invalid{% endif %}">
            <label for="{{ field.id_for_label }}">{{ field.label }}</label>
              <div class="row">
                  <div class="col-6">
                      {{ field }}
                  </div>
              </div>
            {% for error in field.errors %}
              <p class="help-block">{{ error }}</p>
            {% endfor %}
          </div>
    {% endfor %}

I did something like {{ field.first_name }} but this does not show first name form input but if I use {{ field }} all the fields are shown up even the ones I don't want the user to see. How can I select only the fields I want to return to the user?

forms.py

class EmployeeForm(BSModalModelForm):
    class Meta:
        model = EmployeeModel
        fields = "__all__"

views.py

class CreateEmployeeView(BSModalCreateView):
    template_name = 'payrolls/create_employee.html'
    form_class = EmployeeForm
    success_message = 'Success: Employee created'
    success_url = reverse_lazy('payrolls:all_employees')
