feature request for button groups / buttons #463
Description
When using Links in dropdowns the title (or if defined the nav-title) is used for internal links. Links to files can be set but don't have a title or other text in frontend.
Links to external sites, phonenumbers and email-addresses throws an error (PHP Warning: Undefined array key 1 in /var/www/html/vendor/t3sbs/t3sbootstrap/Classes/Components/Button.php line 34).
It would be great to add a field for link-title (like it is given for the button itself) for at least the internal-links and the file-links. Furthermore a hint-text would be helpfull that external-links, phone-links and email-links are not supported/can't be used in this context.
