    @template core/comboboxsearch

    Combobox search selector dropdown.

    Context variables required for this template:
    * rtl - Is this dropdown being used in a RTL case? if so, we need to ensure it drops down in the right place.
    * renderlater - This determines if we show a placeholder whilst fetching content to replace within the placeholder region
    * buttoncontent - The string to be shown to users to trigger the dropdown
    * usebutton - If we want to use a button to trigger the dropdown, or just the dropdown itself
    * dropdowncontent - If rendering now, The content within the dropdown
    * parentclasses - Our class for the DOM Node that the default bootstrap dropdown events are tagged onto
    * buttonclasses - If you want special handling add classes here
    * dropdownclasses - If you want special handling or sizing etc add classes here
    * instance - The instance ID of the tertiary navigation dropdown
