Hi all posting this here so I can understand and others can learn.

Here is a video explaining the problem, and it is outlined again below.

The module needs to unset the default Category List, and replace it with the DropDown Menu.

I have correctly assigned my template to the appropriate list using:

/**
 * @ListChild (list="layout.header.bar", zone="customer", weight="140")
 */

In my XLite\Module\Baby\DropDown\View\DropDown.php class

I now need to unset the template default/en/categories/list/body.tpl called by class XLite\View\TopCategories

I have tried using both:

        \XLite\Core\Layout::getInstance()->removeTemplateFromLists('categories/list/body.tpl');

        \XLite\Core\Layout::getInstance()->removeClassFromLists(
            '\XLite\View\TopCategories'
        );

In my XLite\Module\Baby\DropDown\Main.php, but neither work.

This is due to the class being reassigned to the list by the QSL/WatchWorld module/skin.
In XLite\Module\QSL\WatchWorld\Main.php there is this code:

        \XLite\Core\Layout::getInstance()->addClassToList(
             'XLite\View\TopCategories',
             'layout.header.bar',
             array(
                 'zone'   => \XLite\Model\ViewList::INTERFACE_CUSTOMER,
                 'weight' => 140,
             )
        );

I believe this code is overriding the removeClassFromLists function call in my class. It takes precedence I believe because QSL comes alphabetically after Baby.
To overcome this, I tried decorating \XLite\View\TopCategories and adding this code:

    protected function getDir()
    {
            return '/modules/Baby/DropDown/menu';        
    }

Hoping that it would simply use my template instead. But this causes an error because functions called in my template like getMenu()
Are not relative to the TopCategories Class.

So I overcame it by setting the getDir() function of my decorated TopCategories class to

    protected function getDir()
    {
        if ($this->getParam(self::PARAM_DISPLAY_MODE) == 'list'){
            return '/modules/Baby/DropDown/blank';
        } else {
            return 'categories/' . $this->getParam(self::PARAM_DISPLAY_MODE);    
        }
        
    }

And then created a blank body.tpl in that directory.

This feels wrong. I need to go about this in a better way. Perhaps I can use my decorated TopCategories class and just import the module functions from the DropDown class?
Or should I redefine the functions in the TopCategories class? Or is there something else, that would override the QSL module and allow me to remove that class or template?

How would I do this properly, can you provide a code example please?
