Afficher un nouvel onglet sur la page produit

[Chopin38]

Bonjour,

Je vous écris afin de solliciter un peu d'aide, je pense en effet être arrivé au bout de mes compétences après de longs essais infructueux.

Voici mon problème:

Je souhaite, sur la page d'un produit, pouvoir afficher les descriptions sous forme d'onglets. Je suis parvenu à mettre la page produit sous forme d'onglet, en suivant ce lien :
https://mypresta.eu/en/art/prestashop-16/product-tabs.html

J'arrive donc sur ma page produits, et, pour l'instant, j'ai un onglet "En savoir plus" (affiché en premier par défaut), et un autre "Avis".

J'ai ensuite crée un nouveau champ texte dans la base de données produits, qui s'appelle "pointsforts". J'ai suivi ce tuto:
http://www.paulineghiazza.fr/ajouter-un-champ-dans-le-backoffice-prestashop-1-5/

Je suis parvenu à créer le champ dans le backoffice.

Je bloque désormais pour afficher mon champ "points forts" sur un onglet, et j'aimerai que ce soit le premier onglet par défaut sur la page, suivi de "en savoir plus" et enfin "avis".

Je pense que ça se joue ici (product.tpl):

 

<!-- description and features -->
{if (isset($product) && $product->description) || (isset($features) && $features) || (isset($accessories) && $accessories) || (isset($HOOK_PRODUCT_TAB) && $HOOK_PRODUCT_TAB) || (isset($attachments) && $attachments) || isset($product) && $product->customizable}

Je n'ai compris l'utilisation des idTabs, si je dois en créer une pour mon champ points forts.
Dans le tuto, il est simplement marqué d'insérer le code :
 

{$product->pointsforts}

à l'endroit souhaité.

Si quelqu'un a quelques minutes afin de m'aider, ce serait super sympa,

merci par avance!
