[TYPO3-english] tt_products localisation with sys_language_uid

[Sinsia]

Hi,

I'm using tt_products 2.7.5 and Typo3 4.7.14. I extended tt_products with:

sys_language_uid int(11) DEFAULT '0' NOT NULL,
l18n_parent int(11) DEFAULT '0' NOT NULL,
l18n_diffsource mediumblob NOT NULL,

And also added in TCA

$TCA['tt_products']['ctrl']['languageField'] = 'sys_language_uid';
$TCA['tt_products']['ctrl']['transOrigPointerField'] = 'l18n_parent';
$TCA['tt_products']['ctrl']['transOrigDiffSourceField'] ='l18n_diffsource';

$TCA['tt_products']['columns']['itemnumber']['l10n_mode'] = 'exclude';

In BE there is localisation now, but how do I do that for FE?
Is there any configuration, or did somebody did that?

Best regards,
Sinisa
