Select menu as a configurable display option

Thank you for this useful plugin.

I am not very Grav savvy but managed to modify the code to get a `` menu instead of an `` list. It brought me to the idea to propose it to you as an configurable option.

These are the two files I copied from /user/plugins/langswitcher/templates/partials to /user/themes/[theme]/templates/partials and modified the code to look as follows:



However, I don't know how to add the option to the UI, therefore this feature request.

Start with the two template partials under /user/plugins/langswitcher/templates/partials and the corresponding copies under /user/themes/[theme]/templates/partials. Trace how the plugin exposes configuration in its UI, then make the list/select choice configurable while preserving the existing rendering option. Done means users can choose the display style without manually copying or modifying theme templates.
