Override Silverstripe custom form field template hierarchy

I'm trying to create my own FormField and FieldHolder templates in Silverstripe v3.6.

I've created a FieldList called $Fields and then I loop over its fields to set the custom template on each:

    foreach($Fields->dataFields() as $field) {
        $type = $field->Type();
        // Field holder
        if ($type == "checkbox") {
          $field->setFieldHolderTemplate('CustomCheckboxField_holder');
        } else {
          $field->setFieldHolderTemplate('CustomFormField_holder');
        }
        // Field
        if ($type == "dropdown") {
          $field->setTemplate('CustomSelectField');
        } else if ($type == "optionset") {
          $field->setTemplate('CustomRadioField');
        } else if ($type == "checkbox") {
          $field->setTemplate('CustomCheckboxField');
        } else {
          $field->addExtraClass('custom-form-control');
        }
    }

I've placed the templates in mysite/templates/Includes, eg. CustomCheckboxField.ss drops the normal classes in favour of custom-control-input:

<input $getAttributesHTML("class") class="custom-control-input<% if extraClass %> $extraClass<% end_if %>" />

This works, but only if I include the default FormField.ss and FormField_holder.ss templates in the same folder (copied from framework/templates/forms).

Why do they need to be included, when I'm overriding them? Shouldn't Silverstripe fall back to the originals in the framework folder if they are required? Every one of the fields in my custom form has a custom template (except HeadingFields), so they shouldn't be needed.

I would like to know if I'm doing this correctly. Thank you!

Turns out my problem was due to an error in the documentation for v3.4 that had been picked up along the way. The directory for form field templates should be mysite/templates/forms (NOT Includes).

The answer was found here: SilverStripe custom FormField_Holder
