Six demo BO, however I could not scroll right down to bottom of the side menu to accessibility the module. This is because by default the menu will not scroll, so that you can't see the links to the bottom. You will find a cost-free module accessible to make the menu https://www.presta-addons-modules.com/en/free-modules/prestashop-preloader-page-loading-image-page-loading-animation-preloading-screen-loading-page.html
