we're trying to build a template for the custom field we developed. We don't want to put the template into our theme folder since the template should work between different themes. As far as we know we have the option of putting a custom field.tpl.php somewhere or override theme_field() in our module. What we've been trying with naming these files/functions kind of didn't work out and now we need your help. :-)
What's best practice with building templates / templating for custom fields, where to put it and how to name it?
