Hello, I'm Thang from Vietnam, Have 7 years experience in PHP, CSS, HTML, XML, AJAX, programming. And many platforms such as Oscommerce, Prestashop, Joomla, Wordpress, Ossclass, PhpFox, Opencart, Cs-cart, X-cart, CubeCart...
I'm very interested in working on your project. I have strong skill on Prestashop and i understood your requirement.
I can create an override class to do this. I will modify the product in admin, add a checkbox "Use CMS page". If you click on this checkbox i will hide the main description and show the list of CMS then you can select the CMS you want to show up on product page.
Looking to work with you.
Thank you and best regards.
Thang
